Meeting Abstract P2.10  Friday, Jan. 4  Microhabitat segregation in mimetic ithomiine butterflies HILL, Ryan I.; University of California, Berkeley rihill@berkeley.edu Lowland neotropical butterfly faunas exhibit many �mimicry rings�, in which species from many genera and families share a similar aposematic color pattern. Multiple mimetic patterns is contrary to M�llerian mimicry theory in which unpalatable species share a […]
