Xylesthia pruniramiella, Clemens' bark moth, is a moth of the family Tineidae. It is found in North America, where it has been recorded from New Hampshire to Florida and from Illinois to Texas. The wingspan is 12.7–13.7 mm. The forewings are blackish brown and luteous brown, somewhat varied with whitish, with patches of elevated scales at the base and along the fold and with an indistinct whitish band crossing the middle of the disc, one nearer the base still fainter and one about the end of the disc, with a white dorsal spot at the inner angle and a whitish streak from the costa above it, with another whitish costal streak between this and the tip. There is a blackish spot at the tip which is white margined before. The hindwings are dark brown, somewhat tinged with reddish. Adults are on wing from February to December.
The larvae feed on the woody excrescences found on the branches of the plum tree. Wikipedia →

Rare
Under 5% of wildlife watchers report a Clemens' Bark Moth sighting in Toronto on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1005th most-seen of the 1689 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Clemens' Bark Moth in Toronto on a given day, so our monthly data shows no clear season.

Of the 8 cities where we can rate Clemens' Bark Moth sightings, Toronto ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%), Austin (United States, under 5%) and Dallas (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Clemens' Bark Moth is recorded against all the insects logged in Toronto (11 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.
