Rare
Under 5% of wildlife watchers report a Dusky-Patched Dicymolomia sighting in San Diego on a given day, based on 66 verified sightings from GBIF citizen-science data. It is the 138th most-seen of the 693 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.
June–July and September
In those months about 10% of wildlife watchers report a Dusky-Patched Dicymolomia in San Diego on a given day, against under 5% in August and October–May, the lowest months. Those are among San Diego's driest months, with about 10 mm of rain a month against 55 mm in February.
Yes
Of the 4 cities where we can rate Dusky-Patched Dicymolomia sightings, San Diego has the highest daily chance: under 5%. Next come San Francisco (United States, under 5%) and Portland (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Dusky-Patched Dicymolomia is recorded against all the insects logged in San Diego (66 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.
