Rare
Under 5% of wildlife watchers report a Dusky-Patched Dicymolomia sighting in Portland on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 296th most-seen of the 507 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.
July
In that month about 10% of wildlife watchers report a Dusky-Patched Dicymolomia in Portland on a given day, against under 5% in August to June, the lowest months. That is one of Portland's driest months, with about 10 mm of rain against 250 mm in December.
Among the best
Of the 4 cities where we can rate Dusky-Patched Dicymolomia sightings, Portland ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in San Diego (United States, under 5%) and San Francisco (United States, under 5%).
Same family: Crambidae

GBIF citizen-science records
It is estimated from how often the Dusky-Patched Dicymolomia is recorded against all the insects logged in Portland (13 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.
