Ceropales bipunctata

Ceropales bipunctata , the Two-Speckled Cuckoo Spider Wasp, is a species of diurnal, kleptoparasitic spider wasp in the family Pompilidae. It is an obligate kleptoparasite, meaning that it must rely on the captured provisions of other spider wasps and cannot capture its own. It is found on the Atlantic Coast of North America, north to New Brunswick, Canada. It feeds on nectar primarily from goldenrods (especially Canada goldenrod), and also other common nectaring plants. It is known to lay an egg on the prey of other pompilids, including the two species Anoplius cleora and Anoplius aethiops. Eggs are laid in the book lung of the spider. These wasps also sometimes lay an egg on prey from spider-hunting wasps in the family Sphecidae. rdf:langString
