Leaf-miner Larva - Bedellia somnulentella

Leaf-miner Larva - Bedellia somnulentella
Minneapolis, Hennepin County, Minnesota, USA
August 11, 1999
This was inside a Columbine plant leaf. Is this a Serpentine Leaf Miner larva?

Leaf-mining larva
Did you manage to rear this to the adult? The sigmoid body aspect, green-with-red-spots coloration, and habit of protruding the posterior end of the body out of the mine, all are traits of the larva of a micro moth called Bedellia somnulentella (Bedelliidae). The only snag is that B. somnulentella feeds only on morning glory; any chance that's what this leaf is, rather than columbine?

It was a few years ago when I shot this image, but your comment about the leaf being a morning glory leaf, I do belive that that's actually what it was. We grow lots of varieties of Ipomoea cvr's and I also have several Aquilegia cultivars, but, I do believe that this was a Ipomoea leaf, after all. Thanks for jogging my memory.

 
Correct ID
Bill,
I just updated the guide page for B. somnulentella. The stringy black frass just outside each mine, is distinctive. Larva are also known to feed on sweet potato (Ipomoea).
