A usually greyish species, but abdomen occasionally ferruginous and often with a blackish median and/or lateral longitudinal stripe. The wing length is 18–28 mm. The minimum space between eyes below is at most subequal to the maximum width of
antennal scape; the antennae are 13-segmented. The male tergite 9 has a short median projection (its breadth at base exceeding its length), and roundly bifurcated at apex, the bifurcations blackish; sternite 8 simple, 9 almost fused
with tergite 9 (as in T. paludosa and T. czizeki). female wings as long as abdomen; sternal valves usually extending to about two-thirds length of cerci, cerci only slightly clubbed at tips. Tipula oleracea is prevalent mainly in Europe. Their habitat ranges in the South to North Africa, but has a limit in Algeria to the East. In Europe the South-eastern boundary is in Greece. It occurs on some Greek islands such as Crete as a subspecies... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Marsh Crane Fly is recorded against all the insects logged in Portland (99 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
