Hi, just wondering what kind of caterpillar this is, and what kind of butterfly or moth it might become? I found it today, mid September, in Mutsu (Aomori), thank you!!P. Thanks very much for your submission today and of course for your excellent photograph. It made it a lot easier to identify!Because I was able to carefully check hairs on this caterpillar, I’m pretty certain it’s an  Orgyia thyellina,  ヒメシロモンドクガ (Himeshiro Mondoku-ga)a type of tussock moth.Larval Host Plants:  The caterpillars are generally considered pests as they eat great quantities of human-cultivated plants (alder, rose, beans, mulberry, hops, green beans, apple, and more). Larvae:  The tussock moth family all have very showy caterpillars, with brushy bunches of colorful setae (’hairs’). The caterpillars reach a length of 35-40mm in the final instar. These caterpillars can cause medically significant skin irritation (usually a rash) from a combination of urticating hairs and venom. This caterpillar should NOT BE HANDLED!   You can read more about (American) Tussock Moths at this page. Adult: A small ( ♂21-29 ♀30-42mm) cream-to-brown camouflaged moth, the adult itself is not much to write home about, but they display the characteristic of the genus name Orgyia-- it means “the length of outstretched arms”, and the adult moths always sit at rest with their first pair of legs stretched out forward.Photo Eggs: Cream with a light brown center, laid in wide clusters usually on a vertical surface (ideally a food source for the caterpillars, but moths have been known to make mistakes and deposit eggs on brick walls). -- source link
