Identification
Males and females have different-sized eyes, with the eyes in males taking up much of the head. They also differ greatly in color (though not as apparent in some collection specimens), females being mostly brown and grey/cream colored, while males are covered in bright white hairs.
Specific features of Leucotabanus annulatus include the following: similar in appearance to a small Tabanus, 10-12mm; wings without patterns; antennae typical, with a slight point on top of first flagellomere; small ocelli (simple eyes) on a small tubercle; face of female with a thin callus (shiny area on the forehead), slightly thickening ventrally; male eyes with different facet sizes above and below. (Goodwin et al., 1985)
Range
Throughout much of the eastern US, from Delaware south to Florida, and west to Texas and Kansas. 1
Habitat
Live in places where there are trees and rotting wood. They are found near the coast and inland. 1
Food
As with most other horse flies, L. annulatus will feed on nectar, but females also feed on the blood of vertebrates, including livestock and humans. 1
Larvae are predators found in rotting wood and holes in trees, and some species are known to inhabit termite nests and feed on the colony members. Leucotabanus annulatus is also known to come to lights (Frost, 1953)
