Under 5% of wildlife watchers report a Fluke's Mucksucker sighting in Los Angeles on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 568th most-seen of the 851 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 Fluke's Mucksucker in Los Angeles on a given day, so our monthly data shows no clear season.
Only Los Angeles, in our data

GBIF citizen-science records
It is estimated from how often the Fluke's Mucksucker is recorded against all the insects logged in Los Angeles (10 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.
