Hypena humuli
In 3 days ~10%
Hypena humuli, the hop looper or hop vine moth, is a moth of the family Erebidae. The species was first described by Thaddeus William Harris in 1841. It is found from coast to coast in Canada south in the east to Florida and Arkansas in the west to California. It is apparently absent from the south-central states. In Canada it is only absent from Newfoundland and Labrador, Prince Edward Island and the far north.
The wingspan is 25–32 mm. The moth flies all year round in the south and west and from April to November in the northeast. There are two generations per year northward over most of the east. The larva, or hop worm, is about an inch long when full grown, of a greenish-white color, watery looking or semi transparent, and slightly striped and dotted, having fourteen legs. The mouth is yellowish, and the tips of the jaws black. The larvae appear early in June, and continue until late in August. They feed on Laportea species, hop, nettle and wood nettle. Wikipedia →

Rare
Under 5% of wildlife watchers report a Hop Vine Snout sighting in Toronto on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1296th 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 Hop Vine Snout in Toronto on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Hop Vine Snout sightings, Toronto ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Hop Vine Snout is recorded against all the insects logged in Toronto (7 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.
