A sc-hairy looking caterpillar ...

... this was a big hairy caterpillar I saw at Nam Nao National Park last year. It never stopped eating, even though it was raining quite heavily (hence the water droplets everywhere). Anyone know what species?

Order: Lepidoptera

This shot didn't quite work (it's a bit blurred), but it demonstrates just how hairy he is.
