Omophron labiatum, the large-lipped round sand beetle, is a species of ground beetle in the family Carabidae. It is found in North America, where it inhabits margins of ponds, lakes and rivers in the coastal lowlands. Adults are gregarious and mostly nocturnal and usually hide in burrows in the ground during the day.
The larvae are sometimes considered a pest, because they may feed on grains and corn. Wikipedia →

With luck
About 10% of wildlife watchers report a Large-Lipped Round Sand Beetle sighting in Big Cypress National Preserve on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 193rd most-seen of the 262 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Large-Lipped Round Sand Beetle in Big Cypress National Preserve on a given day, against under 5% in July to March, the lowest months. That is one of Big Cypress National Preserve's driest months, with about 65 mm of rain against 260 mm in June.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Large-Lipped Round Sand Beetle sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Big Cypress National Preserve, in our data
Big Cypress National Preserve is the only park on Wallace's Line with enough records to rate Large-Lipped Round Sand Beetle sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Large-Lipped Round Sand Beetle is recorded against all the insects logged in Big Cypress National Preserve (6 verified sightings from 2019 to 2026), 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.
