Afrotropical, Australian, Indomalayan, Nearctic, Neotropical, Palearctic, and Oceanic regions. Members of this large cosmopolitan subfamily are indigenous worldwide except on the ancient, isolated islands of New Zealand (one species introduced from Australia) and Madagascar. In the Old World the subfamily is especially diverse in the Afrotropical and Indomalayan regions. In the New World the subfamily is most frequent in Mexico, Central America, and the Caribbean Islands. Tropical South America has relatively few species, and native species are unknown from Canada (one species introduced from the Old World), much of the United States, and southern South America.
