Biology

Larvae of Toxomerus apegiensis feed on pollen of Olyra obliquifolia Steudel, a bambusoid grass (Poaceae) that grows in the understorey of tropical rainforests. T. apegiensis and T. politus (Say, 1823), which feeds on pollen of corn (Zea mays), are the only known phytophages within the otherwise predatory genus Toxomerus (Reemer and Rotheray 2009).
