Chlorotabanus crepuscularis
species of insect
Chlorotabanus crepuscularis is a species of horse flies in the family Tabanidae.
This species is the only green tabanid in North America. It can be found from Texas to Delaware. In Florida, this sanguinivorous (blood-feeding) fly is seen as an adult from March through September, but is most active from May to mid-July.
The female has the ability to sense carbon dioxide, which helps it feed on mammals, especially during the night when it is most active. The larvae are also predaceous and live in the soil adjacent to water and on floating vegetation but can also live in forest sand. The insect's blood is blue. The fly's eyes are brown, but glow yellow under 385 nm UV light.
This brief starts where responsible research should: with the source description of “Chlorotabanus crepuscularis” as species of insect. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of insect. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 13, 2026. The linked authority identifier is Q13494310. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
