Across all the parks we cover, that three-hour window holds the most Condylostylus longicornis sightings with a recorded time, and nearly all 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 Condylostylus longicornis is recorded against all the insects logged in San Diego (140 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.
