Summary

Richard South The Moths of the British Isles… (1920)

The habit of the moth is to sit upon the foliage of bushes and the branches of trees, where it might easily be passed over for a fluffy white feather; occasionally it may be found on palings or even iron railings. About dark it is on the wing, and light has then a great attraction for it. The caterpillar is black with black and grey hairs; a vermillion stripe down the middle of the back has a black central line, and is expanded on rings four, eleven, and twelve; along each side there are tufts of snowy white fluffy scales

The caterpillars hatch out in August, and while still very small go into hibernation in a common nest. In the spring, when active again, they construct a new habitation, and another or perhaps two more before they are full grown, about June. The chrysalis is very dark, almost blackish-brown, with tufts of hair, and the fairly substantial brownish cocoon in which it is enclosed is composed of silk and caterpillar hairs, and is spun up on the food-plant, often singly, but not infrequently, several are made up in a common silken covering.

These urticating hairs are more troublesome when received from the caterpillar or cocoon, but those from the moth itself communicate a very respectable simulation of the skin trouble known to the doctor as Urticaria.
The Scarce Vapourer (Orgyia gonostigma) .
The male of this species, and also of the next, flies in the sunshine, but the female of each is wingless, or nearly so, and has to remain at home on the cocoon from which she emerged. Here she lays a large number of eggs, from four to five hundred, upon the exterior. The eggs of this species are whitish and rather glossy when first laid
