Coleophora limosipennella is a moth of the family Coleophoridae described by Philogène Auguste Joseph Duponchel in 1843. It is found in Europe from Fennoscandia to the Pyrenees, Italy and the Balkan Peninsula and from Great Britain to the Baltic States and Romania. It is an introduced species in North America.
The moth flies from June to July depending on the location. Its wingspan is 10–13 mm (0.39–0.51 in). Coleophora limosipennella larvae feed on Ulmus, and supposedly also on Alnus and Betula. Full-grown larvae can be found in June and July. Wikipedia →

Rare
Under 5% of wildlife watchers report a Dark Elm Case-Bearer sighting in Toronto on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 1212th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dark Elm Case-Bearer in Toronto on a given day, so our monthly data shows no clear season.
Only Toronto, in our data
Toronto is the only city on Wallace's Line with enough records to rate Dark Elm Case-Bearer sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dark Elm Case-Bearer is recorded against all the insects logged in Toronto (10 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.
