Gerris gillettei
Lethierry & Severin, 1896
Gerris gillettei is a of water strider ( Gerridae) in the order Hemiptera. It has been studied for intraspecific sexual conflict, with documented intersexual correlations for morphological traits including female connexival spines and male genitalia. The species exhibits -level variation in the balance of sexual armaments between males and females. No-choice mating experiments demonstrate that relative armament levels influence copulation duration.

Behavior
Mating has been experimentally assessed in laboratory conditions. Copulation duration is influenced by both male armament levels and the relative armament levels between males and females. No asymmetries in reproductive behavior or have been detected between sympatric and mating pairs.

Sexual Conflict Research
This has been used as a model to study intraspecific sexually antagonistic . Research has documented significant intersexual correlations for morphological traits related to sexual conflict, suggesting that such coevolution contributed to differentiation. However, the relative importance of female connexival spines versus genitalia traits in mediating pre- and post-copulatory conflict remains unclear.
