Bombylius breviabdominalis
Bombylius breviabdominalis is a species of bee fly in the family Bombyliidae, described by Evenhuis in 1977. As a member of the genus Bombylius, it belongs to a group of flies known for their bee-like appearance and parasitic larval life history. The species epithet "breviabdominalis" refers to its relatively short abdomen. Information specific to this species is limited, though it shares general characteristics with other Bombylius species including a furry body, long proboscis for nectar feeding, and parasitic larvae that develop in the nests of solitary bees.
Bombylius texanus
Bombylius texanus is a species of bee fly in the family Bombyliidae, described by Painter in 1933. As a member of the genus Bombylius, it shares the characteristic fuzzy appearance and long proboscis typical of bee flies, which serve as adaptations for nectar feeding and mimicry of bees. The species is placed within the tribe Bombyliini, whose members are generally active as adults during spring. Like other Bombylius species, B. texanus likely exhibits hovering flight behavior and parasitic larval development, though specific life history details for this species remain poorly documented.
Systoechus
Woolly Bee Flies
Systoechus is a genus of bee flies in the family Bombyliidae, containing more than 120 described species. These flies belong to the tribe Bombyliini and are characterized by their woolly appearance. Adults are primarily active in the fall, distinguishing them from the related genus Bombylius which tends to be active in spring. The genus is distinguished from Bombylius by the location of the r-m vein on the wing.
