Unknown Diptera larva - Phytobia

Unknown Diptera larva - Phytobia
Mont Échoe, Sutton, Cantons de l'Est County, Quebec, Canada
July 8, 2011
Size: 22 mm
I first taught it was a Therevidae larva, but the shape of the posterior spiracles and the dorsum position (and shape) of the anterior spiracles clearly point that it's something else. These caracteres seem very caracteristic, but I still cannot identify it using the key in Nearctic Diptera.

The larva was caught in a pitfall trap in a coniferian forest.

Awesome! This is a very strange Agromyzidae, they live in the cambium of trees and belong to the genus Phytobia...
The anterior spiracle is very characteristic for the family.

Great! Thanks for the identification! I would have never guess an Agromyzidae. In fact, it's were the key in Nearctic Diptera lead me, but I thought it was to big, not to good shape and in the wrong habitat for an Agromyzidae.

It is very unusual for an Agromyzidae, but when you know this one, you can not confuse it with anything else...
