Lomamyia sp..

The genus Lomamyia has four described (and three undescribed) species in Florida: L. banksi, flavicornis, hamata, longicornis. I found this astonishing statement on bugguide: "Eggs are stalked, laid on wood surfaces near termite nests. Larvae live with and prey on termites, using an immobilizing gas (containing an allomone) discharged from their anus." The small image dates 04/26/12.
