Robber fly (female)

Asilidae

Description:

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.

Habitat:

Garden in Tallante, Cartagena (Spain)

Notes:

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.

Sí, Eulalia, tienen un aguijón enorme que utilizan para alimentarse de otras moscas, avispas, abejas, libélulas e incluso saltamontes y arañas, por eso son conocidas también como moscas asesinas.
