This study provides contributions to the knowledge on diversity and natural history of hyperparasitoids (Hymenoptera) associated with host–parasitoid interactions between spiders (Araneae) and polysphinctine Darwin wasps (Pimplinae) in the Atlantic Forest, Brazil, South America. All hyperparasitoids emerged in the laboratory from polysphinctine cocoons that were collected in cocoon webs in the field...
Some polysphinctine parasitoid wasps can alter the web building behavior of their host spiders. In this paper, we describe and illustrate a new species Eruga unilabianasp. nov. and report for the first time, to the best of our knowledge, the interaction between this parasitic wasp and the linyphiid spider Dubiaranea sp. We investigated the wasp's host selection, development, and manipulation of host...
