What Insect Is That?

What is that?

This critter is raising havock in Pollock Pines since the weekend... they have appeared on houses... with the yellow triangle you would think it would be identifiable...

Identified as....

It's Lophocampa (Halisidota) argentata, family Arctiidae--common name Silver-Spotted Tiger Moth (for the adult; search it on Google Images). Common and occasionally eruptive, as apparently now. Hosts pines, firs, and Doug fir; infrequently destructive; young larvae feed in webs like tent caterpillars, but the large ones are solitary. They are off to find a place to spin a cocoon. Adults in June-July.

These little critters will turn into the Silver Spotted Tiger Moth.
