Metoecus paradoxus, also known as the wasp nest beetle, is a species of Metoecus in the family Ripiphoridae. [1]
Description

M. paradoxus measures approximately 10 mm in length. It has a dark head and body and paler, orange-coloured pointed elytra that do not completely cover the abdomen. It has feathery antennae.[2]
Biology and lifecycle

M. paradoxus is primarily a parasitoid of Vespula vulgaris (the common wasp). Adult females lay eggs in decaying wood in autumn, which hatch in spring or summer. The first instar triungulin clings to a V. vulgaris worker to be transported to the nest. Once at the nest, the larva parasitises a wasp larva – once the larva has closed the cell, the M. paradoxus larva consumes the host and pupates in its place. Adults emerge from late July to early October. The development from larva to adult takes less than one month. Adult beetles live for between 6 and 12 days and probably do not feed.[3]
