Under 5% of wildlife watchers report a Marbled Oak Dagger sighting in Sacramento on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 222nd most-seen of the 386 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.
August and September
In those months about 10% of wildlife watchers report a Marbled Oak Dagger in Sacramento on a given day, against under 5% in October to July, the lowest months. Those are among Sacramento's driest months, with almost no rain against 120 mm in December.

GBIF citizen-science records
It is estimated from how often the Marbled Oak Dagger is recorded against all the insects logged in Sacramento (11 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.
