Gymnomerus laevipes is a species from the order of the hymenoptera (Hymenoptera) within the solitary wasps (Eumeninae). It is the only species of the genus in the Palearctic .
features
The wasps reach a body length of 9.5 to 11 millimeters (females) or 8.5 to 10.5 millimeters (males). The animals are drawn yellow-black, with the fifth and sixth tergite colored yellow. Your tegula are rounded at the back. The back of her head is elongated, which makes her head appear quite massive.
Occurrence
The species occurs in central and northern Europe and in southern Europe in the mountains. They colonize different habitats, such as bushes, forest edges, ruderal areas and also occur in the vicinity of humans. Some of the animals also fly in two generations from mid-May to mid-August. They are common in Central Europe in some places.
Way of life
Gymnomerus laevipes makes its nests mainly in the stems of blackberries . To do this, the pulp is gnawed out and the cell is lined with clay. Ultimately, the pith of the stem closes the nest. The brood is supplied with larvae of weevils of the genus Hypera . When the food supply is used up, the larva pupates inside the cell in a spun cocoon on the medullary plug. The overwintering takes place in the larval stage. The species is parasitized by the golden wasps Chrysis fasciata , Chrysis indigotea and Chrysis rutilans .
