Skipper Caterpillar: Juvenal's Duskywing

Caterpillar ID pretty please
November 9, 2009
To my novice eyes this appears to be an early instar, but I’ve had no luck identifying which caterpillar it will grow up to be. I tried looking through your archives but didn’t see it. I don’t want to waste your time. Could you please help? It was chowing down on a Bur Oak in Austin, TX on Nov. 9, 2009. It is approximately 1 inch long. Thanks for your help! I really love your site and have referred to it often.

Dear WTB Fan,
We immediately recognized your unusual caterpillar as a Skipper in the family Hesperiidae, but we were amazed that in about fifteen seconds we identified it as a Juvenal’s Duskywing, Erynnis juvenalis.  According to BugGuide, this wide ranging species has caterpillars that feed on the leaves of oaks.
