Tiger Bee Fly

Fascinating facts about the Tiger Bee Fly

• Adult tiger bee flies are relatively large for their family, measuring about 12-19 mm in body length when the wings, antennae and legs are excluded. This size, together with their black body, often leads observers to mistake them for a large bee during their hovering flight. Their wings are transparent but bear bold, irregular black markings that further enhance the bee-like impression.
• The species' common name and specific epithet tigrinus are derived from its tiger-like wing pattern, a reference to the striking markings on its transparent wings. These bold, irregular black markings set it apart from other bee flies and give the insect its distinctive appearance. The naming highlights this visual trait, linking the Latin term directly to the insect's most noticeable feature.
• The tiger bee fly's larvae develop as parasitoids of carpenter bees, ultimately killing the host as they feed. After a female deposits eggs on the wooden surface near a carpenter bee nest entrance, the hatched larvae crawl inside and consume the developing brood. The eastern carpenter bee, Xylocopa virginica, is the documented primary host, and studies have found the fly to be the most common parasite of this bee's nests.
• Female tiger bee flies first find active carpenter-bee nests that are usually bored into wooden structures. Instead of crawling into the tunnel, they place their eggs on or beside the wooden surface at the nest entrance. The eggs are deposited on the exterior, not inside the cavity. Once the larvae hatch they slip into the nest and consume the developing bee brood.
• Adult tiger bee flies regularly alight on flowers to sip nectar, a behaviour that can aid pollination. Their hovering flight and bee-like size often cause them to be mistaken for large bees while they feed. By moving from bloom to bloom they transfer pollen as they feed. This nectar feeding links them to the plant community as occasional pollinators.
