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.
thanks,

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.

    I am volunteer at the Buena Vista Audubon Nature Center in Oceanside, California. Today, a mother & her 3 children came in with photos & questions about a caterpillar they had seen devouring cattails in our Buena Vista Lagoon. Happily, after consulting your website, we were able to identify them: Cattail Caterpillars/Henry’s Marsh Moth! Thank you “What’s That Bug?” !
