Rare
Under 5% of wildlife watchers report an Iteomyia major sighting in London on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 753rd most-seen of the 1504 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.
June and September
In those months about 10% of wildlife watchers report an Iteomyia major in London on a given day, against under 5% in July–August and October–May, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Iteomyia major sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Iteomyia major sightings, London ranks 2nd at under 5%. The best odds are in Liverpool (United Kingdom, about 10%).
Same family: Cecidomyiidae
The closest relatives of the Iteomyia major that you can see in London (family Cecidomyiidae, Gall and Forest Midges) are Artichoke Gall-Midge (about 10%), Hairy Beech Gall (about 10%) and Locust Gall Midge (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Iteomyia major is recorded against all the insects logged in London (23 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.
