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.
