Why fly now? Photographing moths at porch lights helps us understand their biology and potential environmental threats. John Pickering, Discover Life and the University of Georgia http://www.discoverlife.org/who/Pickering,_John.html Discover Life's Mothing project is studying how weather patterns, urbanization, and other other factors affect insects. Participants have photographed over 500,000 insects in North America and Costa Rica, documenting nightly differences in the activity of over 3,000 species across years and sites. Novel results show how body size of a species can change; how smaller moths are relatively less active than larger moths at colder temperatures; how moths with larvae that feed on lichens are detrimentally affected by urbanization. This talk will focus on flight seasonality, diapause, pupa banks, latitude, and climate change. We wish to involve the public in the project. We are developing Moth Math to teach students how to collect and analyze real-time moth data. There is a wondrous diversity of over 2,700 moth species in Georgia. Use your cell phone to help us find and map the dark dozen! For details see www.discoverlife.org/moth .
