Reproduction in spider wasps includes many larval stages that feed off a single spider. The female lays a single egg on the abdomen of the spider. The female then uses its abdomen to enclose the nest space with loose soil. As the larva grows it feeds off the spider, leaving the heart and central nervous system for last. There are no major differences in the five larval stages of the spider wasp except for size. During the fifth larval stage, the spider wasp will wrap itself in a silk cocoon where it will emerge as an adult in either late summer, or over winter. This depends on the species and the time of year (Garman and Punzo).
