In 3 days ~10% in a week ~20%
Gnorimoschema gallaesolidaginis, the solidago gall moth, goldenrod gall moth or goldenrod gallmaker, is a moth in the family Gelechiidae. It was described by Riley in 1869. It is found in North America, where it has been recorded from Alberta, British Columbia, California, Florida, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, New Brunswick, New Hampshire, New York, North Carolina, Ohio, Oklahoma, Ontario, Pennsylvania, Quebec, Tennessee, Texas and Wisconsin.
The forewings are deep purplish-brown, more or less sprinkled with carneous (the color of flesh). A light carneous band starts from the costa near the base, and curves towards the middle of the inner margin, which it occupies to a little beyond the beginning of the cilia, where it curves upwards towards the tip, reaching only halfway up the wing. Here, it is approached from above by a somewhat diffuse spot of the same colour, which starts from the costa just behind the apex, and runs down to the middle of the wing. The hindwings are slate-gray.
The larvae feed on Solidago nemoralis, Solidago altissima and Solidago gigantea. They form spindle-shaped galls on their host plant. Wikipedia →

Rare
Under 5% of wildlife watchers report a Goldenrod Elliptical-Gall Moth sighting in Boston on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 967th most-seen of the 1200 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Goldenrod Elliptical-Gall Moth in Boston on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Goldenrod Elliptical-Gall Moth sightings, Boston has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Goldenrod Elliptical-Gall Moth is recorded against all the insects logged in Boston (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.
