In addition, a species in that genus which is totally new to science was also discovered. The new species, Spasskia brevicarinata, is very small — male and female […]

Videos of Parasitoid Wasps and their Caterpillar Hosts

This first video was recently submitted to the 2013 ESA YouTube Your Entomology contest by Justin Bredlau, a PhD student at Virginia Commonwealth University. The video shows the life of the parasitic wasp, Cotesia congregata, and two of its hosts. It includes courtship behavior, parasitizing of the host, and larval egression. More information on the […]
