Dear Friends:
I found this caterpillar in a typical grassy meadow (perhaps brome grass, Bromus inermis), at the beginning of this month (October 2008). I’m sometimes able to figure out things by searching them on-line but this one stumped me. I don’t often see bright caterpillars this late in the year.

Hi Gavin,
We are surprised as how quickly we located your Cattail Caterpillar, Simyra insularis, on BugGuide. Because the caterpillar feeds on cattail, smartweed, grasses, sedges, poplar and willow, the habitat includes marsh edges, wooded riverbanks, and generally any damp area where larval foodplants grow.  The adult is also known as Henry’s Marsh Moth.
