Coleophora spinella
In 3 days ~10%
Coleophora spinella, the apple-and-plum casebearer, is a moth of the family Coleophoridae. It is found in Europe, the Near East and North America. The wingspan is 10–12 mm. Coleophora species have narrow blunt to pointed forewings and a weakly defined tornus. The hindwings are narrow-elongate and very long-fringed. The upper surfaces have neither a discal spot nor transverse lines. Each abdomen segment of the abdomen has paired patches of tiny spines which show through the scales. The resting position is horizontal with the front end raised and the cilia give the hind tip a frayed and upturned look if the wings are rolled around the body. C. spinella characteristics include forewing fuscous, ochreous brown or greyish without longitudinal streaks or white markings. The antenna are white with fuscous rings.
C. spinella can only be reliably identified by dissection and microscopic examination of the genitalia. The moth flies from June to July depending on the location. The larvae feed on Crataegus, apple, Prunus cerasus, Prunus spinosa (and perhaps other Prunus), Pyrus communis (and perhaps other Pyrus species), Sorbus and Cotoneaster. Wikipedia →

Rare
Under 5% of wildlife watchers report an Apple-And-Plum Casebearer Moth sighting in Toronto on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1135th 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 an Apple-And-Plum Casebearer Moth 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 Apple-And-Plum Casebearer Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Apple-And-Plum Casebearer Moth is recorded against all the insects logged in Toronto (9 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.
