Argyrotaenia quadrifasciana, the four-lined leafroller moth, four-banded leafroller or lesser all-green leafroller, is a species of moth of the family Tortricidae. It is found in North America, where it has been recorded from Nova Scotia to West Virginia, west to Arkansas and north to Alberta. The habitat consists of orchards and shrubby areas.
The wingspan is about 14–17 mm. Adults have been recorded on wing from May to August in one generation per year. The larvae feed on the leaves of Amelanchier species (including Amelanchier alnifolia), Crataegus species, Malus sylvestris, Prunus species (including Prunus pensylvanica, Prunus serotina, Prunus virginiana) and Pyrus species. The species overwinters as a third-instar larva. Wikipedia →

Rare
Under 5% of wildlife watchers report a Four-Lined Leafroller Moth sighting in Toronto on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1410th 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 Four-Lined Leafroller 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 Four-Lined Leafroller 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 Four-Lined Leafroller Moth is recorded against all the insects logged in Toronto (6 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.
