About the Ladybird Parasitoid Wasp
Dinocampus coccinellae is a braconid wasp parasite of coccinellid beetles, including the spotted lady beetle, Coleomegilla maculata. It is the only species in the genus Dinocampus. D. coccinellae has been described as turning its ladybird host into a temporary "zombie" guarding the wasp cocoon. About 25% of Coleomegilla maculata recover after the cocoon they are guarding matures, although the proportion of other ladybird species which recover is much lower.
In 1802, Schrank first described a female adult of this species as "Lady-bird killer 2155. Deep black, eyes green; head, front legs, and apex of the petiolate abdomen mussel-brown." (A petiolate abdomen is one whose basal segment is stalk-like, that is, long and slender.) Nearly all D. coccinellae are female offspring of unfertilized eggs, although males are also occasionally found. The male, when observed, has no ovipositor and is slimmer and darker than females.
The mature female wasp seeks out adult female ladybirds, although they will sometimes oviposit into a male adult or larval instar. One egg is planted in the host's soft underbelly. The wasp larva hatches after 5–7 days into a first instar... Wikipedia →
