Chrysoperla mutata (McLachlan, 1898), known from northern Africa, southern Europe, and western Asia, was found on Tenerife, the largest of the Canary Islands. Larval and adult morphology as well as acoustic song analysis confirm that the Tenerife species is indeed C. mutata, not the closely related African C. pudica (Navás, 1914). The fact that the two specimens were found at two places close to the Tenerife South International Airport, and never before on the well-sampled Canary Islands, suggests that C. mutata is a newly established immigrant species.
