Omophron limbatum, the spangled button beetle, is a species of beetle of the Carabidae family. This species is found in Great Britain, Denmark, Sweden, France, Belgium, Netherlands, Germany, Switzerland, Austria, Czechia, Slovakia, Hungary, Poland, Estonia, Latvia, Lithuania, Belarus, Ukraine, Portugal, Spain, Italy, Slovenia, Croatia, Bosnia-Herzegovina, former Yugoslavia, Serbia, North Macedonia, Albania, Greece, Bulgaria, Romania, Moldova, Algeria, Tunisia, Syria, Turkey, Iran, Georgia, Armenia, Azerbaijan, Kazakhstan, Uzbekistan, Kyrgyzstan, Tadzhikistan, Afghanistan and Russia. Its habitat consists of the sandy margins of fresh water.
Adults reach a size of 5-6.5 mm and are pale yellow to brown in colour with metallic green markings. Omophron limbatum lives on sandy riverbanks which are exposed and they are very sensitive to habitat changes such as dam construction and vegetation overgrowth. This makes it a good indicator of environmental disturbance. Wikipedia →

Rare
Under 5% of wildlife watchers report a Spangled Button Beetle sighting in Wadden Sea National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 536th most-seen of the 818 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.
July and August
In those months about 10% of wildlife watchers report a Spangled Button Beetle in Wadden Sea National Park on a given day, against under 5% in September to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Spangled Button Beetle sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Wadden Sea National Park, in our data
Wadden Sea National Park is the only park on Wallace's Line with enough records to rate Spangled Button Beetle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Carabidae
The closest relatives of the Spangled Button Beetle that you can see in Wadden Sea National Park (family Carabidae, Ground Beetles) are Northern Dune Tiger Beetle (about 10%), Dune Tiger Beetle (about 10%) and Granulated Ground Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spangled Button Beetle is recorded against all the insects logged in Wadden Sea National Park (7 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.
