Male damselflies detect female mating status: Importance for postcopulatory sexual selection

Article Abstract:

Model organisms are used to test the relative importance of sperm competition and cryptic female choice for copulation duration in laboratory experiments. It is concluded that even in odonates, where sperm removal is widespread, females have retained control over sperm reserves in their spermatheca, and males prolong copulation with mated females to elicit rival sperm ejection and to induce females use their sperm in fertilization.

Mechanisms for the formation and maintenance of traditional night roost aggregations in a territorial damselfly

Article Abstract:

A study is conducted into the communal roosting behaviour of rubyspot damselflies, in association with territorial status and sex. The results of field tests for specific models of roost formation and maintenance are evaluated.
