Dinetus pictus is a hymenoptera fromthe Crabronidae family .
features
The animals reach a body length of 6 to 9 millimeters (females) or 5 to 7 millimeters (males). There is a clear sexual dimorphism between the two sexes . The abdomen of the females is red-black in color and has yellow spots on the sides. The male has a yellow-black spotted abdomen and spiral antennae.
Occurrence
The species occurs in Europe as far as northern Germany, in Poland and in southern Finland. It colonizes very dry and temperature-favored habitats with open sandy areas. The animals fly in one generation from early June to early September. The species is rare in Central Europe.
Way of life
The females of Dinetus pictus often create their nests in small aggregations. The nest consists of a six to seven centimeter long, initially inclined, then vertically downward-pointing passage. The female transports the excavated material particularly quickly, flying backwards out of the entrance. The nest entrance is always locked. The brood is supplied with larvae and rarely also adults of sickle bugs . Both sexes spend the night in corridors around two centimeters deep, which are quickly excavated in the evening. The species is parasitized by Chrysis bicolor .
