Parasitoids present an unusual life cycle: they cannot be classified as parasites because of a free-living stage, but their eggs and larvae must develop inside a host. Unlike classic parasites, parasitoid activity ends with the death of the host. There are over 30,000 species of parasitoid wasps, with some species parasitizing other wasp larvae. Though their lifecycle is somewhat grotesque, they perform an important ecological role in managing the populations of their hosts, the tomato hornworm in the case of C. congregata. This poster illustrates the unique lifecycle of C. congregata, highlighting the spatial and size differences of the wasp as it grows from its first larval stages under the cuticle of the hornworm, to its emergence and pupal stage inside a cocoon, and its adult stage outside the host.
This poster applied skills acquired over the course of a semester; all models were sculpted and painted in Pixologic zBrush, lit in Keyshot 8, and composited in Adobe Photoshop.
