Status: Resident

Coordinator notes: Correct ID; a very one-of-a-kind caterpillar. Alders are actually one of their less commonly used host plants (they normally prefer willows and poplars). With a willow thicket nearby, I’m surprised the adult moth chose to lay her eggs on alder instead of willow.
