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!

Genus: Glaphyropyga

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.

Hola amigo Jesús,
Maybe this species is common in your area, but the photo is unique. A superb close up full of details and with excellent sharpness. I can't even imagine how close you (rather your camera) were to the fly! Fantastic job, an image to be proud of. Bravo MF.
Friendly regards, László

E questa e' una macro spettacolare,sei troppo bravo,che dettagli,nitidezza e perfetta messa a fuoco.Un capolavoro!

Hi Jesus,
I am not much up on my South American insects but I challenge anyone to find a more detailed crisp macro than this one. Wow its fantastic, bravo to you.


Sometimes I wonder is that really possible with a compact camera? That quality I mean! No, ... I do not questioning the facts here, but this truly is an unbelievable quality friend Jesus! Great detail, sharpness and clarity! What an incredible control again. All the features of the Robber Fly is easily readable. By the way what is this strange thing, attached to the insect butt?

Hello Jesús,
A very fine macro of this species of Robberfly taken with excellent sharpness and natural colours against a neutral BG.
Great that you could find the ID of this species, which must be even more difficult than naming butterflies!
Thanks and have a nice Sunday,
Regards from a totally white Sweden,
