Of all the active, vigilant creatures that animate our paths, we have

none superior to the little, bee-like bombylius (bombylius medius); but

this creature is to be seen only in the mornings of a few bright days in

spring, seeming to delight in the hot, windy gleams of that season,

presenting an emblem of that portion of our year, fugitive and violent.

It is, I believe, plentiful nowhere. Particularly solicitous of warmth,

it seeks the dry sunny reflection of some sheltered gravel-walk, or

ditch-bank in a warm lane; and here it darts and whisks about, in

seeming continual suspicion or danger; starting away with angry haste,

yet returning immediately to the spot it had left; buffeting and

contending with every winged fly that approaches, with a jealous,

pugnacious fury, that keeps it in constant agitation. This action, its

long projecting proboscis, and its pretty, spotted wings, placed at

right angles with its body, distinguish our bombylius from every other

creature. It appears singularly cautious of settling on the ground.

After long hovering over and surveying some open spot, with due

deliberation and the utmost gentleness it commits its long, delicate

feet to the earth; but on the approach of any winged insect, or on the

least alarm, is away again to combat or escape. Associates it has none:

the approach even of its own race excites its ire, and, darting at them

with the celerity of thought, it drives them from its haunts. When a

captive it becomes tame and subdued, and loses all its characteristic

bustling and activity, the inspiration of freedom.

The great black ant (formica fuliginosa) is commonly found in all little

copses, animating by its numbers those large heaps of vegetable

fragments, which it collects and is constantly increasing with unwearied

industry and perseverance as a receptacle for its eggs. The game-fowl,

the woodpecker, the wryneck, and all the birds that feed upon the little

red ant, and soon depopulate the hillocks which they select, do not seem

equally to annoy this larger species. These systematic creatures appear

always to travel from and return to their nests in direct lines, from

which no trifling obstacle will divert them; and any interruption on

this public highway they resent, menacing the intruder with their

vengeance. A neighbor related to me an instance of this unyielding

disposition, which he witnessed in one of our lanes. Two parties of

these black ants were proceeding from different nests upon a foraging

expedition, when the separate bodies happened to meet each other.

Neither would give way; and a violent contest for the passage ensued.

After a time the combat ceased, and all animosity subsided, each party

retiring to its nest, carrying with it its dead and maimed companions.

This encounter seemed quite accidental, and the disposition to move in a

uniform line, which their meeting prevented, the sole cause of their

hostility, combat, and mutual injury. The strength of some creatures,

especially insects, considering the smallness of their size, is in

several instances prodigious. Man, by his reason and power, calls to his

aid mechanical means, and other agents, to effect his objects; but

unreasoning beings accomplish their purposes by contrivance and bodily

powers. The strength of these black ants is manifested by the quantity

and magnitude of the materials which they collect for their heaps; but

the common little red ant (formica rubea), a much smaller creature,

gives daily proofs of its abilities to remove heavy substances, equal to

any that we meet with. One of these little creatures, thirty-six of

which only weigh a single grain, I have seen bear away the great black

fly as its prize, equal to a grain in weight, with considerable ease;

and even the wasp, which exceeds forty times its own weight, will be

dragged away by the labor and perseverance of an individual emmet. These

little ants are occasionally and profusely deprived of their lives by

some unknown visitation. In the year 1826, in particular, and again in

the following year, I observed, in the month of August, a lane strewed

with their bodies. They had bred during the summer in an adjoining bank;

but some fatality had overwhelmed them when absent from their nests, and

nearly annihilated the fraternity, as only a few scattered survivors

were to be seen feebly inspecting the bodies of their associates. The

task of removal, however, with all their industry, appeared beyond their

powers to accomplish, as on the ensuing day few had been taken away. Had

these creatures been destroyed in combat by rival contention, the

animosity must have been excessive; but it is more probable that they

met their death by some other infliction.

One year, on the 3d of March, my laborer being employed in cutting up

ant-hills, or tumps, as we call them, exposed to view multitudes of the

yellow species (formica flava) in their winter’s retirement. They were

collected in numbers in little cells and compartments, communicating

with others by means of narrow passages. In many of the cells they had

deposited their larvæ, which they were surrounding and attending, but

not brooding over or covering. Being disturbed by our rude operations,

they removed them from our sight to more hidden compartments. The larvæ

were small. Some of these ant-hills contained multitudes of the young of

the woodlouse (oniscus armadillo), inhabiting with perfect familiarity

the same compartments as the ants, crawling about with great activity

with them, and perfectly domesticated with each other. They were small

and white; but the constant vibration of their antennæ, and the alacrity

of their motions, manifested a healthy vigor. The ants were in a

somewhat torpid state; but on being removed into a temperate room, they

assumed much of their summer animation. How these creatures are

supported during the winter season it is difficult to comprehend, as in

no one instance could we perceive any store or provision made for the

supply of their wants. The minute size of the larvæ manifested that they

had been recently deposited; and consequently that their parents had not

remained during winter in a dormant state, and thus free from the calls

of hunger. The preceding month of February, and part of January, had

been remarkably severe; the frost had penetrated deep into the earth,

and long held it frozen; the ants were in many cases not more than four

inches beneath the surface, and must have been inclosed in a mass of

frozen soil for a long period; yet they, their young, and the onisci,

were perfectly uninjured by it; affording another proof of the fallacy

of the commonly received opinion, that cold is universally destructive

to insect life. Some creatures may be injured or destroyed by frost, but

the larger portion of them nature has provided with constitutions to

which it is innocuous, or furnished with instinct to prevent its harming

them. These emmets had probably received no substance, or required any,

from the time of their retirement in the autumn, a period of full six

months; were inclosed during the space of thirty days in a mass of

frozen earth, and yet remained perfectly uninjured by this long

abstinence and frost.

Water, in a state of rest over decayed and putrescent vegetable matter,

is peculiarly favorable for the residence of many of the insect world.

The eggs that are lodged there remain undisturbed by the agitation of

the element, and the young produced from them, or deposited there by

viviparous creatures, remain in quiet, tolerably secure from accidental

injuries; but there are natural causes which render these apparent

asylums the fields of ravenousness and of death. To these places resort

many of those voracious insects and other creatures, which prey upon the

smaller and helpless; for all created things seem subordinate to some

more powerful or irresistible agent, from the hardly visible atom that

floats in the pool, to man, who claims and commands the earth as his

own. But we have no animal that seems to commit greater destruction in

these places than the common newt (lacertus aquaticus). In some of these

well-stored magazines this reptile will grow to a large size, and become

unusually warty, and bloated with repletion; feeding and fattening upon

the unresisting beings that abound in those dark waters wherein it loves

to reside. It will take a worm from the hook of those that angle in

ponds; and in some places I have seen the boys in the spring of the year

draw it up by their fishing-lines, a very extraordinary figure, having a

small shell-fish (tellina cornea) attached to one or all of its feet;

the toes of the newt having been accidentally introduced into the gaping

shell, in its progress on the mud at the bottom of the pool, or

designedly put in for the purpose of seizure, when the animal inhabitant

closed the valves and entrapped the toes. But from whatever causes these

shells became fixed, when the animal is drawn up hanging and wriggling

with its toes fettered all round, it affords a very unusual and strange

appearance.

Water, quiet, still water, affords a place of action to a very amusing

little fellow (gyrinus natator), which about the month of April, if the

weather be tolerably mild, we see gamboling upon the surface of the

sheltered pool; and every schoolboy, who has angled for a minnow in the

brook, is well acquainted with this merry swimmer in his shining black

jacket. Retiring in the autumn, and reposing all the winter in the mud

at the bottom of the pond, it awakens in the spring, rises to the

surface, and commences its summer sports. They associate in small

parties of ten or a dozen, near the bank, where some little projection

forms a bay, or renders the water particularly tranquil; and here they

will circle round each other without contention, each in his sphere, and

with no apparent object, from morning until night, with great

sprightliness and animation; and so lightly do they move on the fluid,

as to form only some faint and transient circles on its surface. Very

fond of society, we seldom see them alone, or, if parted by accident,

they soon rejoin their busy companions. One pool commonly affords space

for the amusement of several parties; yet they do not unite, or contend,

but perform their cheerful circlings in separate family associations. If

we interfere with their merriment they seem greatly alarmed, disperse,

or dive to the bottom, where their fears shortly subside, as we soon

again see our little merry friends gamboling as before.

This lively little animal, arising from its winter retreat shortly after

the frog, at times in March, continues its gambols all the summer long,

remaining visible generally until the middle of October, thus enjoying a

full seven months of being; a long period of existence for insects,

which are creatures subject to so many contingencies, that their lives

appear to be commonly but brief, and the race continued by successive

productions. All these water creatures must be endowed with much

perception. Cold as this element is in early spring, when the ice of

winter is hardly dissolved, and the fluid only 6 or 7 degrees above

freezing, yet they become immediately sensible of this temperature, and

are excited to animation and the vocations of their being. I have never

observed the larvæ of this creature in any state. When they retire in

the autumn, these insects appear of a uniform size, and emerging in the

spring they are all apparently full grown, and during the summer none of

smaller dimensions associate with the family parties. This plain, tiny,

gliding water-flea seems a very unlikely creature to arrest our young

attentions; but the boy with his angle has not often much to engage his

notice; and the social, active parties of this nimble swimmer,

presenting themselves at these periods of vacancy, become insensibly

familiar to his sight, and by many of us are not observed in after life

without recalling former hours, scenes of perhaps less anxious days: for

trifles like these, by reason of some association, are often remembered,

when things of greater moment pass off, and leave no trace upon our

mind.

July 29.—We frequently notice in our evening walks the murmuring

passage, and are often stricken by the heedless flight, of the great

dorr beetle[63] (scarabæus stercorarius), clocks,[62] as the boys call

them. But this evening my attention was called to them in particular by

the constant passing of such a number as to constitute something like a

little stream; and I was led to search into the object of their direct

flight, as in general it is irregular and seemingly inquisitive. I soon

found that they dropped on some recent nuisance: but what powers of

perception must these creatures possess, drawn from all distances and

directions by the very little fetor, which in such a calm evening could

be diffused around! and by what inconceivable means could odors reach

this beetle in such a manner as to rouse so inert an insect into action!

But it is appointed one of the great scavengers of the earth, and

marvellously endowed with powers of sensation, and means of effecting

this purpose of its being. Exquisitely fabricated as it is to receive

impressions, yet probably it is not more highly gifted than any of the

other innumerable creatures, that wing their way around us, or creep

about our path, though by this perceptible faculty, thus “dimly seen,”

it excites our wonder and surprise. “How wondrous then the whole!”

This creature affords us a good example of that extraordinary artifice,

to which some insects have recourse upon the apprehension of danger, the

counterfeiting of death. The dorr, with a violent and noisy flight,

proceeds on its way, or circles around with an apparent fearlessness of

harm; yet the instant it is touched, or interrupted in its progress,

though in no way injured, it will immediately fall to the ground,

generally prostrate on its back, its limbs extended, stiff, and

seemingly devoid of life, and suffering itself to be handled without

manifesting any signs of animation. In time, finding no harm ensues, it

resumes its former state. If our conjectures be correct, that the object

of this stratagem is to preserve its life, it is difficult to comprehend

how far it can be successful. Several birds feed on it, as we observed;

and that others do so likewise is evident from their castings. Of these,

the owl and the nightjar catch it when on the wing; and the crows,

rooks, magpies, &c., seem to have no hesitation in picking it to pieces,

as well as all the other beetles, that put on the semblance of death, in

whatever state they find them. One or two beasts, it is said, when

captured, feign death. With these exceptions, we remember none of the

other orders of creation, that have recourse to such an expedient upon

any emergency; but with insects it is by no means an uncommon procedure,

most probably resorted to by them for a motive we are not fully

acquainted with, and which is in all likelihood attended with the

success it was designed to effect.

The perfect cleanliness of these creatures is a very notable

circumstance, when we consider that nearly their whole lives are passed

in burrowing in the earth, and removing nuisances; yet such is the

admirable polish of their coating and limbs, that we very seldom find

any soil adhering to them. The meloe, and some of the scarabæi, upon

first emerging from their winter’s retreat, are commonly found with

earth clinging to them; but the removal of this is one of the first

operations of the creature; and all the beetle race, the chief

occupation of which is crawling about the soil, and such dirty employs,

are notwithstanding remarkable for the glossiness of their covering, and

freedom from defilements of any kind. But purity of vesture seems to be

a principal precept of nature, and observable throughout creation.

Fishes, from the nature of the element in which they reside, can

contract but little impurity. Birds are unceasingly attentive to

neatness and lustration of their plumage. All the slug race, though

covered with slimy matter calculated to collect extraneous things, and

reptiles, are perfectly free from soil. The fur and hair of beasts in a

state of liberty and health is never filthy, or sullied with dirt. Some

birds roll themselves in dust, and occasionally, particularly beasts,

cover themselves with mire; but this is not from any liking or

inclination for such things, but to free themselves from annoyances, or

to prevent the bites of insects. Whether birds in preening, and beasts

in dressing themselves, be directed by any instinctive faculty, we know

not; but they evidently derive pleasure from the operation, and thus

this feeling of enjoyment, even if the sole motive, becomes to them an

essential source of comfort and of health.

It may be noted probably by some, how frequently I recur to the causes

and objects of the faculties, manners, and tendencies of animate and

inanimate things. This recurrence springs from no cavil at the wisdom,

no suspicion of the fitness of the appointment, nor, I trust, from any

excitement to presumptuous pryings into paths which are in the great

deep, and not to be searched out; but are humbly indulged, from the

pleasure which the contemplation of perfect wisdom, even in a state of

ignorance, affords; and if by any consideration we can advance one point

nearer to the comprehension of what is hidden, we infinitely increase

our satisfaction and delight.

May 24, 1827.—Abundance of cockchaffers (melolantha vulgaris) are flying

about, yet by no means in the profusion of some years. How much at times

the interest of man and the wild creatures about him are at variance!

Those that are domesticated and precluded from obtaining food but by his

permission, have their welfare in part identified with his—they may

share in his abundance, or pine from his parsimony; but the independents

of the field are differently circumstanced. The appearance of these

chaffers, in any numbers, is very uncertain and partial, but in those

summers when they abound, very extensive injuries frequently ensue. In

the grub state, they will entirely destroy the pastures where they

inhabit, by consuming the roots of the grasses; acres and fields are

deprived of their produce, becoming brown as stubbles, with only a sprig

or tuft of green useless vegetation observable in them; the grain crop

likewise totally fails when the larvæ of this chaffer feeds in the

field. Upon assuming their winged state, they devour the foliage of the

oak and other trees so effectually, that entire copses may be seen early

in June defoliated by their depredations. So much for their injury to

man: but now the feast of the wilding commences—the plow in April

dislodges multitudes of these long white grubs. Dogs then seek them

eagerly to eat, but they seem to be surfeited by the food; for, though

fattened at first, they afterwards become diseased, and lose their hair.

Rooks and crows are running over the ridges, busily seeking for this

larvæ; the swine find it out, and come in for their share, and having

finished here, they commence grubbing in the grass lands. The insect now

soon takes wing, and then every tree in the wood or the brake becomes a

scene of plunder and delight to all the train from the rookery—the cats

will eat him—every sparrow that flies by has a chaffer in its mouth,

captured on the wing or snatched from the spray, and now to be pecked to

pieces on the ground—the thrush feasts too, and all the poultry in the

yard are running after chaffers, or chasing each other for the prize;

and thus this insect supplies in one state or another a general feast to

many.

Surrounded as we are by wonders of every kind, and existing only by a

miraculous concurrence of events, admiration seems the natural avocation

of our being; nor is it easy to pronounce amidst such a creation what is

most wonderful. But few things appear more incomprehensible than the

constant production and reabsorption of matter, impressed upon us even

by these very dorrs. An animal falls to the ground and dies; myriads of

creatures are now summoned by a call, by an impulse of which we have no

perception, to remove it, and prepare it for a new combination; chemical

agencies, fermentation, and solution, immediately commence their actions

to separate the parts, and in a short time, of all this great body,

nothing remains but the framework or bones, perhaps a little hair or

some wool, and all the rest is departed we know not whither! Worms and

insects have done their parts; the earth has received a portion, and the

rest, converted into gases, and exhalable matters, has dispersed all

over the region, which, received into vegetable circulation, is again

separated and changed, becomes modified anew, and nourishes that which

is to continue the future generations of life. The petal of the rose;

the pulp of the peach; the azure and the gold on the wing of the insect;

all the various productions of the animal and vegetable world; the very

salts and compounds of the soil, are but the changes some other matters

have undergone, which have circulated through innumerable channels since

the first production of all things, and no particle been lost; bearing

in mind this assured truth, that all these combinations have not been

effected by chance or peculiarity of circumstances, but by the

predetermination of an Almighty Intelligence, who sees the station,

progress, and final destination of an atom, what an infinity of power

and intellective spirit does this point out! an omnipotence, which the

bodied minds of us poor creatures cannot conceive. Truly may we say,

“who can find out the Almighty to perfection?”

Our extensive cultivation of the potato furnishes us annually with

several specimens of that fine animal the death’s-head moth[64]

(acherontia atropos), and in some years I have had as many as eight

brought me in the larva or chrysalis state. Their changes are very

uncertain. I have had the larva change to a chrysalis in July, and

produce the moth in October; but generally the aurelia remains unchanged

till the ensuing summer. The larvæ or caterpillars, “strange ungainly

beasts,” as some of our peasantry call them, excite constant attention

when seen, by their extraordinary size and uncommon mien, with horns and

tail, being not unusually five inches in length, and as thick as a

finger. This creature was formerly considered as one of our rarest

insects, and doubtful if truly indigenous; but for the last twenty

years, from the profuse cultivation of the potato, is become not very

uncommon in divers places. Many insects are now certainly found in

England, which former collectors, indefatigable as they were, did not

know that we possessed; while others again have been lost to us moderns.

Some probably might be introduced with the numerous exotic plants

recently imported, or this particular food may have tended to favor the

increase of rarely existent natives; but how such a creature as this

could have been brought with any plant is quite beyond comprehension. We

may import continental varieties of potatoes, but the death’s-head moth

we have never observed to have any connexion with the tuber itself, or

inclination for it. As certain soils will produce plants by exposure to

the sun’s rays, or by aid of peculiar manures, when no pre-existent root

or germ could rationally be supposed to exist; so will peculiar and long

intervening seasons give birth to insects from causes not to be divined.

We may perhaps conclude, that some concurrence produced this sphinx, and

then its favorite food, the potato plant, nourished it, to the

augmentation of its species.
