Abstract
The discovery of a lowland Amazonian wing-dimorphic carabid species, c olliuris batesi Chaudoir, prompted a complete study of its biology and behaviour over a period of more than 4 years. Studies were made on de velopment, fecundity, gonad development, life span and habitat shifts. Survival strategies and possible adaptations are examined with respec t to seasonal flooding of their habitat. It is proposed that evolution of brachyptery in this species is rather recent in origin because mac ropterous specimens are widespread across the upper Amazon Basin, and because the only body change associated with short wings has been narr owing of the humeri.
