Tabanus autumnalis
species of insect
Tabanus autumnalis, the large marsh horsefly, is a medium-sized species of biting horse-fly. It is somewhat scarce compared to T. bromius and T. bovinus. This species shows slightly more of a preference for coastal marsh than some of the other European Tabanus, sometime even found in saltmashes.

Eyes without coloured bands. Male: postocular edge almost covered by the eyes and with a short fringe. Palps: second segment oval. Female: postocular edge narrower; interocular 4-5-6 times longer than wide; median plate bare, joining the lower one. Antennae: third segment with a blunt or short tooth. Wing has a hyaline costal cell.Abdomen: dorsal side with a lateral line of light spots placed between the midline and the lateral edge of the tergites, so that on the black background you can see five light longitudinal lines: one median, two lateral, and two marginal, separated from each other by four black lines. Wing length is 13–16 mm and about 16–22 mm in body length.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Tabanus autumnalis”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q1617236. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
