Description
Tachytes etruscus can reach a length of 15–16 millimetres (0.59–0.63 in) in female, of 11–14 millimetres (0.43–0.55 in) in males. Body is largely black, with silver stripes on the abdomen and brown to ferruginous wings, legs, mandibles and palpi.
Biology
Females of this species usually predate on grasshoppers. The females dig holes in the ground in which they build some cells. 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. The larva consumes the prey during development. Males apparently guard the entrance of the burrows with developing females, waiting for them to emerge. These wasps have a preference for flowers of Solidago virgaurea and Echinophora spinosa.
