Rare
Under 5% of wildlife watchers report a Yellow-Veined Moth sighting in San Diego on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 269th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow-Veined Moth in San Diego on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Yellow-Veined Moth is recorded against all the insects logged in San Diego (25 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.
