Ripiphoridae (formerly spelled Rhipiphoridae) is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches or beetles. Many species of Ripiphoridae have abbreviated elytra, and flabellate or pectinate antennae. Biology The subfamily Ripiphorinae parasitise bees and wasps (Hymenoptera), while Ripidiinae parasitises cockroaches (Blattodea) and Pelecotominae parasitises larvae of wood-boring beetles (Coleoptera). Species that attack bees typically lay their eggs on flowers. There the eggs hatch almost immediately into small planidial larvae and lie in wait for a visiting host. The planidium mounts the bee and rides it back to the hive. There i ...
