Rare
Under 5% of wildlife watchers report a Girdler Moth sighting in San Diego on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 556th most-seen of the 693 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Girdler Moth in San Diego on a given day, so our monthly data shows no clear season.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Girdler Moth sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Girdler Moth is recorded against all the insects logged in San Diego (7 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.
