The female's clypeus is flat, the tarsal crest is colorless to light yellow. The male has a central lobe with side corners on the clypeus. The tarsi on the front legs have a bristle comb.
Occurrence

It colonizes temperature-favored bare to loosely vegetated habitats with loose sand. The animals fly in one generation from late May to mid-August. The species is rare in Central Europe.
Way of life
The females of Tachytes helveticus create their nests in loose sand. Only one cell is created per nest. The brood is supplied with two to four larvae of field locusts . The egg is deposited between the hips of the host's front and middle legs . The nest is finally closed with the help of the abdomen. The pupation of the larva takes place in a firm, sand-strewn cocoon . The adults rarely visit flowers.
