Rhynocoris tristis is a species of assassin bug family (Reduviidae), in the subfamily Harpactorinae. R. tristis is a polyphagous predator found in sub-Saharan Africa.[1]

Life History

R. tristis is associated with Stylosanthes guinaensis, and this association is thought to be due to the prey species attracted by flowers of S. guinaensis.[2] R. tristis is unusual in the insect world in that males provide paternal care by guarding egg masses.[3] from parasitic wasps and insect predators.[1] Males will also cannibalize some of the eggs that they guard.[4] R. tristis prefers to lay its eggs on the stems of plants, in contrast to most members of the harpactorinae, which prefer to lay them on the undersides of leaves.[1]
