Chionodes obscurusella, the boxelder leafworm moth, is a moth in the family Gelechiidae. It is found in North America, where it has been recorded from Nova Scotia to Manitoba, south to North Carolina and Oklahoma. The wingspan is about 12 mm. The forewings are dull ochreous fuscous spotted with black, with a small black sub-costal dot at the base of the wing. There is a small black dash from the basal third of the costa, below and beyond this and occupying about the middle of the cell is a broad ill-defined patch of blackish scales. There is a more or less obscure shading of black scales on the middle of the costa, as well as a black dash just before the apical third of the costa, and below it, extending to the dorsum, an irregular, ill-defined black line. A faint dusting of black scales is found near the outer margin of the wing. The hindwings are very pale, semi-transparent whitish-fuscous.
The larvae are leaf-tiers on Acer negundo and Acer saccharum. Wikipedia →

Rare
Under 5% of wildlife watchers report a Boxelder Leafworm Moth sighting in Edmonton on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 295th most-seen of the 390 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.
October
In that month about 10% of wildlife watchers report a Boxelder Leafworm Moth in Edmonton on a given day, against under 5% in November to September, the lowest months.
Only Edmonton, in our data
Edmonton is the only city on Wallace's Line with enough records to rate Boxelder Leafworm 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 Boxelder Leafworm Moth is recorded against all the insects logged in Edmonton (8 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.
