Joseph Deas, Ph.D. candidate (EIS-GIDP) and advisor discovered seed beetles use eggs as shield against wasps

Doctoral candidate Joseph Deas in the University of Arizona's Graduate Interdisciplinary Program in Entomology and Insect Science, along with his faculty advisor Martha Hunter in the department of entomology, is peering into their world through his microscope and has discovered something novel: The beetles, whose eggs frequently are parasitized by the wasp Uscana semifumipennis, have a strategy to protect their offspring that goes beyond a helpful habit.
"They're stacking their eggs in order to protect them from these parasitic wasps," said Deas, whose research appears in the Proceedings of the Royal Society B on Sept. 14.
