Eucyrtopogon albibarbus
Curran, 1923
Eucyrtopogon albibarbus is a of robber fly in the Asilidae, described by Curran in 1923. The Eucyrtopogon contains small to medium-sized predatory flies that can be confused with the related genus Comantella. Both genera share traits such as early spring and late fall activity, a humpbacked profile, and ground-perching in open .

Identification
Eucyrtopogon are distinguished from the similar Comantella by antennal structure: Eucyrtopogon lacks the slender spur on the tip of the front tibia that characterizes Comantella. Specific identification of E. albibarbus relies on the relative length of the terminal antennal style compared to the third antennal segment, and the coloration of body hairs. Members of this genus are 10–15 mm in length, covered in long hair including on the legs, with a pronounced thoracic 'mane' resembling a Mohawk hairstyle.
Habitat
Open fields with bare soil; perch on the ground rather than on vegetation.
Seasonality
active in early spring and late fall; may overwinter in protected places.
Behavior
perch on bare ground in vast open fields. Predatory on other arthropods.
Ecological Role
in open field .
Similar Taxa
- ComantellaShares humpbacked profile, seasonal timing (early spring/late fall activity), and ground-perching in open . Distinguished by presence of a slender spur on the front tibia (absent in Eucyrtopogon) and antennal proportions.
