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 →

Rare
Under 5% of wildlife watchers report a Marsh Crane Fly sighting in San Francisco on a given day, based on 132 verified sightings from GBIF citizen-science data. It is the 125th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March to May
In those months about 10% of wildlife watchers report a Marsh Crane Fly in San Francisco on a given day, against under 5% in June to February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Marsh Crane Fly sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 25
Of the 25 cities where we can rate Marsh Crane Fly sightings, San Francisco ranks 16th at under 5%. The best odds are in Salt Lake City (United States, about 10%), Portland (United States, about 10%) and Boston (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Marsh Crane Fly is recorded against all the insects logged in San Francisco (132 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.
