Rare
Under 5% of wildlife watchers report a Dusky-Patched Dicymolomia sighting in San Francisco on a given day, based on 133 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 737 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 to September
In those months about 10% of wildlife watchers report a Dusky-Patched Dicymolomia in San Francisco on a given day, against under 5% in October to June, the lowest months. Those are among San Francisco's driest months, with almost no rain against 110 mm in December.
Among the best
Of the 4 cities where we can rate Dusky-Patched Dicymolomia sightings, San Francisco ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in San Diego (United States, under 5%).
Same family: Crambidae
The closest relatives of the Dusky-Patched Dicymolomia that you can see in San Francisco (family Crambidae, Crambid Snout Moths) are Genista Broom Moth (about 10%), Volupial Mint Moth (about 10%) and California Pyrausta Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dusky-Patched Dicymolomia is recorded against all the insects logged in San Francisco (133 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.
