Silk cocoons of parasitoid wasps on Manduca sexta paphus, Sphingidae

Description:

Silk cocoons made by larvae of very small parasitoid wasps on a sphingiid caterpillar. Having consumed much of the caterpillars tissues they are now preparing for metamorphosis. The caterpillar has little chance of completing its own metamorphosis. The credit for the explanation goes to Gustavo Acccio, a Brazilian entomologist.
