The adults of the Conopidae are 14 mm long, diurnal and are often found at flowers and feed on nectar.
Their larvaes are endoparasites, actually in bees and wasps. The copulation varies from about 20 minutes up to 2 hours, while the male is positioned above the female. Females wait on plants to attack foraging wasps or bees to place their eggs on the host. If more then one egg is placed in a single host, only one larva will survive. In the final stage of the attack, the Conopidae can mimic the zig-zag flight of it’s target. The larvae penetrate into the abdomen of the hosts. After the hibernation in the dead host, the Conopidae hatch out again.
