Tipula paludosa, known as the European crane fly and its larva as leatherjacket, is a species in the genus Tipula, a genus of over 2,000 species distributed throughout the world. T. paludosa is native to northwestern Europe including Britain and Ireland, and also introduced to the northern aspects of North America, including Canada likely due to soil dispersion and other human-mediated activities. T. paludosa is often regarded as a pest of lawns, pastures, and hayfields, as its larvae cause significant damage to the roots, stems, and leaves of various plants, contributing to its invasiveness.
Tipula paludosa, at the adult stage, have greyish-brown bodies that are 1.5–2.5 cm long, with long, thin legs. Males have shorter bodies and large wings. The pupae are 3.0–3.5 cm long, with the mature being slightly larger at 3–4 cm. Females can lay about 200–300 eggs, which appear egg-shaped, are shiny black, and are about 1 mm long. Ventral spacing between the eyes of T. paludosa is twice the width in males and females compared to other species of Tipula. T. paludosa has 14 antennal segments for both males and females. The female abdominal length ratio is a... Wikipedia →

Rare
Under 5% of wildlife watchers report a European Crane Fly sighting in Seattle on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 253rd most-seen of the 428 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a European Crane Fly in Seattle on a given day, against under 5% in October to August, the lowest months. That is one of Seattle's driest months, with about 60 mm of rain against 190 mm in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most European 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.
21st of 22
Of the 22 cities where we can rate European Crane Fly sightings, Seattle ranks 21st at under 5%. The best odds are in Rotterdam [The Hague] (Netherlands, about 10%), Liverpool (United Kingdom, about 10%) and Amsterdam (Netherlands, about 10%).
GBIF citizen-science records
It is estimated from how often the European Crane Fly is recorded against all the insects logged in Seattle (12 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.
