Biology: Some species of Lispoides have aquatic larvae that are predators of many kinds of invertebrates (Skidmore 1985).

Comments: Lispoides insularis is an endemic species from Juan Fernández Archipelago. Hennig (1955) identified three females from Alejandro Selkirk Island as belonging to this species, which he did not describe at the time. Later Hennig (1957) described L. insularis based on one male and two females from Alejandro Selkirk Island (Table 1).
