Specimen type: Photograph
Observation notes: This caterpillar seems to be overwintering in this spot, however I've only just noticed it for the first time and I walk by the wall I found it on every day after school. The top was fastened to the wall with a pad of silk. The "bag" was made of twigs that seem to be from a conifer in the genus Thujopsis, however there weren't any trees nearby, just a few "Thuja" shrubs which are routinely trimmed.
