“…(a) Study organism and measurement of traits The ambush bug P. americana Melin (Heteroptera: Phymatidae) is a sit-and-wait predator of flower-visiting insects (Balduf 1939(Balduf , 1941. Its colour pattern is complex, consisting of a mostly yellow integument with dark (black or brown) patches (figure 1).…”

Sexual dimorphism in coloration is a taxonomically widespread phenomenon often attributed to sexual selection on visual signals. However, the ambush bug Phymata americana exhibits sexual dimorphism in coloration that has no apparent signalling function. Here we provide evidence that colour pattern in this species influences male mating success indirectly through its effect on thermoregulation. We demonstrate, using experimental manipulation, that individuals with dark colour pattern achieve higher thoracic temperatures under illumination. We also show that dark colour pattern predicted mate-searching success but only under thermally challenging conditions (i.e. cool ambient temperature). As far as we are aware, this is the first study to provide evidence that sexual dimorphism can be accounted for by sexual selection on thermoregulatory performance.

“…The Nabidae, Miridae, Lygaeidae, Coreidae, and Pentatomidae are commonly found on fl owers with easily accessible nectar, such as the Compositae and Umbelliferae (see 255). Some Phymati dae use flowers as places to ambush prey (19). In the case of the Heteropt era, there is little information on the importance of the anthophilous habit to either the insects or the plants.…”
