Abstract
The distribution and flight behaviour of libellulid dragonflies was studied in clearings of a lowland, tropical, moist forest on Barro Colorado Island, Panama (January - February 1986). The numbers
of individuals and species increases with clearing area. Maximum flight activity up to the canopy is at
noon with increasing light intensity. In the afternoon only short flights can be observed near the ground.
There are two groups of different coloured libellulids, which are distinguished in their height, kind and
density of perching sites. These differences are discussed as strategies to avoid potential predators.
