Pterocheilus phaleratus is a hymenoptera from the family of the wasps (Vespidae). It is the only species of its genus in Europe. Several subspecies are known of the species.
features
The animals reach a body length of seven to nine millimeters. The scales on the wing joint ( tegulae ) are rounded at the back. The labial palps are very long and long ciliate. The species has the longest mouthparts of solitary wasps, making them sand between them and the Prothorax can transport well.
Occurrence
The species occurs in Europe to the south of Scandinavia. It colonizes dry and temperature-favored, open, sparsely vegetated habitats with sandy soils. The animals fly from mid-May to mid-September. The species is rare in Central Europe.
Way of life
The nest is made in the sandy soil. It goes a few centimeters straight down and ends in a single cell that branches off horizontally. The egg is glued to the ceiling in it. Then the larval food, caterpillars, is brought in by real bag carriers (Psychidae). The entire corridor is then filled with sand. In the imagos nectar robbery (can Kleptolektie ) are observed. They bite open flowers, especially those of common horn clover or ox-tongue , and suck nectar through this opening without pollinating the flower.
