From host plants to host ants: phyto-predation and phylogeny of Lepidochrysops butterflies and relatives.
MCZ 101, 26 Oxford Street, Harvard University
More than 99.99% of the approximately 200,000 described Lepidoptera species are phytophagous. Only around 500 species are aphytophagous and feed mainly on other insects or their secretions. Aphytophagy is most common in the butterfly family Lycaenidae where it has evolved independently several times, but mostly as single species in otherwise phytophagous clades. One exception is the Afrotropical genus Lepidochrysops, with 137 described species, all assumed to be predaceous on ant brood or fed by trophallaxis from the third instar until pupation. Little is known about their life history, the relationships among the five genera in the Euchrysops section, and even less about the relationships among species within Lepidochrysops. Dr Espeland’s aim is to infer a phylogeny of the Euchrysops section and answer questions about the evolution of predation and diversification of the group.
The talk is free and open to the public. The meeting is readily accessible via public transportation. Parking is available in the Oxford Street Garage with advance arrangement, as described here, or (usually but not always) at spaces on nearby streets. Everyone is also welcome to join us for dinner before the talk (beginning at 6:00 PM) at the Cambridge Common, at 1667 Massachusetts Ave.
CEC meetings are held the second Tuesday of the month from October through May. The evening schedule typically includes an informal dinner (6:00 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 50 minute entomology related presentation. Membership is open to amateur and professional entomologists.
