Knulliana is a genus of longhorn beetles. It is monotypic, being represented by the single species Knulliana cincta, commonly known as the banded hickory borer. The species may be found throughout the eastern half of North America, including Mexico and the Bahamas, with one subspecies extending to the Sonoran Desert.
They are typically found on hickory and oak trees, where they lay eggs in crevices in the bark or directly into the wood. During their first season, the larvae feed beneath the bark, and later bore deeper into the wood. They sometimes cause significant damage to their host trees.
The banded hickory borer ranges in length from 15 to 35 mm (0.6 to 1.4 in). They have strong spines on the femora, pronotum, and on the tips of the elytra. There are three described subspecies: Knulliana c. cincta (Drury) – eastern North America, Texas
Knulliana cincta ochracea (Bates) – south-eastern United States, north-eastern Mexico, Bahamas Knulliana cincta sonorensis (Schaeffer) – Texas to Arizona, adjacent regions in Mexico Wikipedia →

GBIF citizen-science records
It is estimated from how often the Banded Hickory Borer is recorded against all the insects logged in Dallas (31 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.
