Archips packardiana
In 3 days ~10%
Archips packardianus, the spring spruce needle moth or spruce needleworm, is a species of moth of the family Tortricidae. Spruce needle worms are commonly found in small numbers on spruce and trees of other coniferous genera throughout most of Canada and the northeastern US (Rose and Lindquist 1985).
Archips packardiana overwinters as a tiny larva in a mined needle. Needle mining is resumed in the spring, the larvae later moving to feed on new foliage, where they spin considerable webbing. Full-grown larvae have a pale green head, sometimes patterned with brown, and a pale body and pale thoracic legs, and are about 20 mm long.
The larva pupates, usually in the webbed needles, and the adult emerges in summer to early fall. The closely related Archips strianus is much less common, but probably has a habitat similar to that of A. packardiana (Rose and Lindquist 1985). The larvae have dark thoracic legs and small dark areas around the base of the thoracic hairs. The habitat consists of coniferous and mixed woods.
The wingspan is about 17 mm. Adults have been recorded on wing in April and from June to October. The larvae feed on the needles of Picea and Abies species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Spring Spruce Needle Moth sighting in Toronto on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1212th 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 Spring Spruce Needle 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 Spring Spruce Needle 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 Spring Spruce Needle Moth is recorded against all the insects logged in Toronto (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.
