Movement patterns and behavior of Calopteryx aequabilis Say (Zygoptera: Calopterygidae) in Nova Scotia, Canada

A population of individually marked Calopteryx aequabilis was monitored daily during summer 1982 along a 630 m section of stream draining agricultural fields in the Canard Valley, Kings County, N.S. Among adults, resident males were more site-specific than experimentally introduced males or resident females. After emergence, tenerals remained near the stream. Teneral males became significantly more site-specific and were subject to increased mortality and/or dispersal as they matured. Oviposition was usually attended by males, and occurred both at the surface and when females were fully submerged.
