Similar somewhat to the English Gamma, or silver Y
moth, but a distinct variety, and found largely in Europe.
The fore-wings are dark ashy-grey, with bronze
markings, and have a pale golden mark in the middle
resembling the letter r. The hind-wings are brown, of
a lighter shade towards the base. It measures in expanse
about two inches; the antennæ are long and fine.
The larva, which is green with a yellowish stripe at the
sides, feeds on the potato and other low-growing plants,
and is found during the early spring months, and well
on into the summer.
