I recently collected some large, hairy yellow striped caterpillars for my grade 3 Science class. One of them has just emerged from its cocoon as a yellow moth about 3 centimeters in length. When I googled ”yellow moth”none of the images showed a moth quite like this one.

Possibly Lappet Moth Caterpillar

Hi Alan,
Both your caterpillar and the adult moth remind us of the North American Lappet Moths in the family Lasiocampidae, and even more specifically, those in the genus
Phyllodesma.  Here is a comparison photo of a North American caterpillar from BugGuide, and here is an adult moth also from BugGuide.  Though the coloration is quite different, the manner in which the moth holds its underwings in relation to the upper wings is strikingly similar.  Again, this is just a guess, and we hope to be able to provide you with additional information on our own as well as through reader contributions.

We immediately tried a search of the family in Thailand and found a Moths of Borneo website, and on Plate 6, and there is an image of a mounted specimen identified as a female Trabala ganesha that looks remarkably like your moth.  Here is a photo from the Foto Biodiversitas Indonesia website and an even better match are these images of Trabala vishnou from Thailand on this Taxonomy website: http://193.166.3.2/pub/sci/bio/life/insecta/lepidoptera/ditrysia/bombycoidea/lasiocampidae/trabala/index.html.
