Chalcidoid Wasps and the Interface of Systematics and Biology

John Heraty
Department of Entomology, University of California, Riverside

Abstract:

Chalcidoid wasps may be the most diverse group of insects on the planet, and yet they are very poorly understood or even recognized. The talk will focus on their diversity, some unusual biologies, and touch on their phylogenetics and the future classification of the group. There will be a more detailed look a group of ant-parasitoid chalcidoid wasps, the Eucharitidae. These wasps deposit their eggs remote from the host and the first-instar larvae have a series of unusual behaviors that they use to get into the ant nest where they attack the ant brood. Equally important, eucharitid adults have unique behaviors and means of chemical mimicry to get themselves out of the nest. Overall, it is a combination of natural history, taxonomy and phylogeny that help us to better understand these fascinating insects.

Due to visitor restrictions on Harvard campus and COVID-19 social distancing guidelines, we are temporarily suspending all physical meetings and formal pre-talk dinners until further notice. 

CEC meetings are normally held the second Tuesday of the month from October through May. The evening schedule typically includes an informal dinner (5:45 to 7:15 PM) followed by our formal meeting (7:30 – 9:00 PM). The latter begins with club business and is followed by a 60-minute entomology related presentation. Membership is open to amateur and professional entomologists.

The ecology of collective behavior

Deborah Gordon
Department of Biology, Stanford University

PC: Deborah Gordon

Abstract:

Collective behavior operates without central control, using local interactions among participants to allow groups to respond to changing conditions. Ant colonies function collectively, and the enormous diversity of more than 14,000 species of ants, in different habitats, provides opportunities to look for general ecological patterns. I will contrast two ant species: harvester ants that (Pogonomyrmex barbatus) live in the desert,  where water is limited but conditions are stable, and the arboreal turtle ant (Cephalotes goniodontus ) that lives in the canopy of the tropical forest, where activity is easy but conditions are unpredictable. These examples suggest how collective behavior evolves to respond to changing situations.
