Seasonal incidence of Anisoptera in light-traps in Trinidad, West Indies
Odonatologica , Volume 10 - Issue 3 p. 179- 187
Forty-nine Anisoptera, comprising 19 sp. and 13 genera, were captured on about 11% of nights at risk in 2 light-traps operated nightly in Trinidad for 14 months. Most spp. and individuals were captured during the rainy season (June through December). ’Older’ adults predominated in catches at the beginning and end of the rainy season, and ’younger’ adults about 3 months after its onset. The results are consistent with the assumption that old adults, having retired to shaded refuges, provide continuity during the dry season and then, at the start of the rains, become active in exposed situations and promptly reproduce, adults of the ensuing generation emerging 2-4 months later.
