features

The very small, black and almost hairless animals have a short abdomen stalk. The front wings have a very large wing mark that is almost as large as the marginal cell.

Way of life

Typically for the Pemphredoninae , the females build their nests in stems and abandoned drill holes in dead wood. The brood is supplied with aphids , which are grabbed with the mandibles in flight . The individual cells of the nests are separated from the corridor of the nest by gnawing off material.
