Lucanus capreolus, the reddish-brown stag beetle or pinching beetle, is a beetle of the family Lucanidae. The specific name capreolus is derived from Latin, meaning "roe deer" (capreolus literally means "little goat"). The name refers to the resemblance of the mandibles to deer antlers.
A relatively large lucanid beetle of the genus Lucanus, the male has long, curved upper jaws, resembling a sickle. The larvae are found in the trunks of old trees, feeding on the inner wood. It is dark reddish brown with smooth, shiny elytra (“wing cases”); the femora are orange brown. Males have much larger jaws than females. Jaws of males are not as large as those of Lucanus elaphus. The smaller L. placidus has two or more teeth on its jaws and has dark femora. It is 22–35 mm long.
The species was originally described by Carl Linnaeus as Scarabaeus capreolus in his 1763 Centuria Insectorum. (orig. comb.). As with most of the species of the Lucanidae, sexual dimorphism is pronounced, and the male of Lucanus capreolus is larger than the female and armed with mandibles... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Reddish-Brown Stag Beetle is recorded against all the insects logged in Detroit (51 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.
