Horse Fly Larvae

This horse fly larva (family Tabanidae) was collected in late July in a pond on the shoulder of the Uncompahgre Plateau.  I've heard that tabanid larvae will eat frogs, and now I absolutely believe it.  The larvae can inflict a more painful bite to humans than the adults. Thanks to Jennifer Bonnell for the picture and to Boris Kondratieff for the identification as either Tabanus punctifer or T. atratus.
