Flea Beetle: Disonycha leptolineata

Potato beetle?
March 29, 2010
I recently found this guy in the woods behind my house. At first he lay on his back on played dead, but then he flipped over and crawled away. He looks kind of like a potato beetle, but I wasn’t sure at all.

Flea Beetle

Hi Stephen,
The well developed femora of the rear leg identifies this as a Flea Beetle in the tribe Alticini of the Skeletonizing Leaf Beetle subfamily Galerucinae.  We believe it is Disonycha leptolineata based on images posted to BugGuide.

Wow, thank you very much!  Your site is really amazing, and it’s cool to get a response so quickly, too!  By the way, here is a picture of him playing ‘possum, in case you’re interested.
