Host-seeking behavior in larvae of the robber fly Mallophora ruficauda (Diptera: Asilidae)
The robber fly Mallophora ruficauda is the most important pest of apiculture in the Pampas region of Argentina. Adults prey on honeybees and other insects, while larvae parasitize larvae of scarab beetles, which live underground. Females of M. ruficauda do not search for hosts but instead lay eggs i...
