In 3 days ~10%
Oidaematophorus eupatorii, the eupatorium plume moth or Joe Pye plume moth, is a moth of the family Pterophoridae. It is found in North America, including Florida, Mississippi, Iowa, New York, California and Vancouver Island. It is also known from Mexico, Guatemala and Panama.
The wingspan is about 21–24 millimetres (0.83–0.94 in). The head is dull reddish brown and the thorax is pale brown. The legs are brown. The forewings are pale ocher yellow, whitest on the costal portion, and sprinkled with dark-brown scales to such an extent as to give them a wood-brown color. These dark-brown scales form a spot, nearly reaching a dark-brown costal streak over the end of the fissure, beyond which are two costal dark-brown spots, the first of which is the smaller. The fringes are smoke brown, cut with whitish once on the first lobe and twice on the outer margin of the hind lobe. The hindwings and fringes are brownish cinereous.
The larvae are greenish, striped with wine color and white, and feed on Eupatorium species (including Eupatorium purpurascens) and Epilobium species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Joe-Pye Weed Plume Moth sighting in Chicago on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 751st most-seen of the 978 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 Joe-Pye Weed Plume Moth in Chicago on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Joe-Pye Weed Plume Moth sightings, Chicago has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Joe-Pye Weed Plume Moth is recorded against all the insects logged in Chicago (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.
