• Dinocampus coccinellae

  Ladybird Parasitoid Wasp

  Dinocampus coccinellae is a solitary braconid wasp that parasitizes lady beetles (Coccinellidae). The female wasp deposits a single egg into the host's abdomen, where the larva develops through four instars over 18–27 days before emerging. Upon emergence, the larva paralyzes the host and spins a cocoon attached to the ladybird's legs. The paralyzed host remains alive, twitching occasionally, and serves as a protective bodyguard that deters predators with its bright coloration and defensive movements. Approximately 25% of hosts recover after the wasp completes development. The wasp is notable for co-injecting Dinocampus coccinellae paralysis virus (DcPV) with its egg, which facilitates host manipulation.
