Micrurapteryx salicifoliella is a moth of the family Gracillariidae. It is known from Canada (Québec, Alberta, Saskatchewan, Manitoba, the Northwest Territories) and the United States (including Missouri, Ohio, Illinois, Minnesota, Alaska, Vermont, Kentucky, Michigan, Texas, California).
The wingspan is about 9 mm. Adults are on wing in mid to late July in Illinois, with a possibly a second generation emerging in October. In California, adults can be found from April to October and in Texas in November. The larvae feed on Populus species (including Populus balsamifera, Populus tremuloides and Populus grandidentata) and Salix species (including Salix alba, Salix arbusculoides, Salix babylonica, Salix bebbiana, Salix brachycarpa, Salix exigua, Salix glauca, Salix integra, Salix interior, Salix lasiandra, Salix longifolia, Salix monticola, Salix novae-angliae, Salix planifolia and Salix scouleriana). They mine the leaves of their host plant. Wikipedia →

Rare
Under 5% of wildlife watchers report a Willow Leaf Blotch Miner Moth sighting in Edmonton on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 336th 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.
September
In that month about 10% of wildlife watchers report a Willow Leaf Blotch Miner Moth in Edmonton on a given day, against under 5% in October to August, the lowest months.

Across all the parks we cover, that three-hour window holds the most Willow Leaf Blotch Miner Moth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Edmonton, in our data
Edmonton is the only city on Wallace's Line with enough records to rate Willow Leaf Blotch Miner 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 Willow Leaf Blotch Miner Moth is recorded against all the insects logged in Edmonton (5 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.
