Deltochilum gibbosum, the humpback dung beetle, is a species of dung beetle in the family Scarabaeidae. It is a member of subgenus Hybomidium Shipp, 1897 and is found in the southeastern United States. A variety described by Henry Walter Bates in 1887, D. gibbosum var. sublaeve, has been classified as a separate species D. sublaeve by González-Alvarado and Vaz-de-Mello. The same authors regard D. gibbosum subsp. panamensis Howden, 1966 as a separate species D. panamensis. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Humpback Dung Beetle is recorded against all the insects logged in Everglades National Park (12 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.
