Tachytes etruscus is a predatory, solitary wasp belonging to the family Crabronidae.

[2] This species is present in Albania, Austria, Bulgaria, France, Greece, Hungary, Italy, Portugal, Russia, Slovenia and Spain.

Its body is largely black, with silver stripes on the abdomen and brown to ferruginous wings, legs, mandibles and palpi.

Then they capture a prey grasshopper, paralyze it with a sting, carry it inside the underground nest and seal it in the burrow along with an egg.

Males apparently guard the entrance of the burrows with developing females, waiting for them to emerge.
