I’ll keep the ball rolling with Arctiinae and post a photo today of Ctenucha brunnea. This moth can be common in tall grasses along beaches from San Francisco to LA – although in recent decades the numbers of this moth have been declining with habitat destruction and the invasion of beach grass (Ammophila arenaria). But anywhere there are stands of giant ryegrass (Leymus condensatus) you should find dozens of these moths flying in the heat of the day or nectaring on toyon.

Waw. what a stunner!
