Semiotus ligneus is a species of click beetle from Central and South America. It grows to a total length of 15–44 millimetres (0.6–1.7 in), and is 3.7–4.2 times as long as it is wide. The larvae are 27 mm (1.1 in) long. It closely resembles seed sheaths, which provides it with effective camouflage.
S. ligneus is the most frequently collected species in the genus Semiotus. Its closest relative is Semiotus serraticornis. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Semiotus ligneus is recorded against all the insects logged in Tambopata National Reserve (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.
