Furnished with a trowel--the ordinary garden kind will do, but the flatter
pattern, sold by dealers, is better--the collector may take a turn at
digging at the roots of trees for chrysalids. No doubt there are many kinds
to be obtained in this way, but I cannot say much for the practice, as my
own efforts have not been very highly rewarded. Not a single species was
ever obtained by digging that I could not have secured more easily in some
other way.
Methods of setting, and after-manipulation have been fully discussed in
"Butterflies of the British Isles."
