Anthrax (fly)

The genus Anthrax belongs to the family Bombyliidae, commonly known as bee flies. These flies are found globally and are characterized by their robust build, often dark coloration, and intricate wing patterns. Many species within Anthrax are parasitoids, meaning their larvae develop inside or on other insects, ultimately killing their host. A common host for Anthrax larvae are the larvae and pupae of various Lepidoptera (moths and butterflies), beetles, and other fly species.

Adult Anthrax flies are often seen hovering near the ground or around potential host habitats, searching for suitable hosts on which to lay their eggs. The female fly typically deposits her eggs near the host insect. Upon hatching, the Anthrax larva actively seeks out the host and begins to feed, eventually consuming it entirely.

The genus Anthrax can be differentiated from other bee flies by specific morphological features, including wing venation patterns and the shape of the head and thorax. While some species within Bombyliidae are pollinators, Anthrax species are primarily recognized for their parasitic lifestyle and their role in regulating populations of other insect species.
