Glaphyropyga bolivari - Ayala, 1983

I have recently seen some Asilidae flies here in TN, then I go walk around to shot one today, in order to share with you in TN. Here these flies are easy to find; a few hundred meters from my house, runs a small river and there some local farmers have their mules and cattle there, these ugly flies abound! ...

Find ID of this fly is very complicated also there are little information on the web for local species. But it seems to me that this is a Glaphyropyga bolivari - Ayala, 1983 the most common of our Asilidae flies.

Thanks by stop and visit!

About this family: Insects in the Diptera family Asilidae are commonly called robber flies. The family Asilidae contains about 7,100 described species worldwide.

All robber flies have stout, spiny legs, a dense moustache of bristles on the face (mystax), and 3 simple eyes (ocelli) in a characteristic depression between their two large compound eyes. The mystax helps protect the head and face when the fly encounters prey bent on defense. The antennae are short, 3-segmented, sometimes with a bristle-like structure called an arista.

The short, strong proboscis is used to stab and inject victims with saliva containing neurotoxic and proteolytic enzymes which paralyze and digest the insides; the fly then sucks the liquefied meal through the proboscis. Many species have long, tapering abdomens, sometimes with a sword-like ovipositor. Others are fat-bodied bumblebee mimics. Adult robber flies attack other flies, beetles, butterflies and moths, various bees, ants, dragon and damselflies, Ichneumon wasps, grasshoppers, and some spiders.
