Abstract

The leaf-top herbivore guild of Heliconia spp. is a particularly good subject for the examination of host colonization because individuals may be monitored easily for extended periods of time. Studies of the guild on H. imbricata in Costa Rica and on H. latispatha in Ecuador reveal substantial variation in the rates of colonization among plants. The variation is explained best by the insects' response to environmental conditions, in particular, light and moisture.
