Rare
Under 5% of wildlife watchers report a Grape Flea Beetle sighting in Miami on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 326th most-seen of the 826 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 Grape Flea Beetle in Miami on a given day, so our monthly data shows no clear season.
Only Miami, in our data

GBIF citizen-science records
It is estimated from how often the Grape Flea Beetle is recorded against all the insects logged in Miami (23 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.
