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 →

Rare
Under 5% of wildlife watchers report a Banded Hickory Borer sighting in Houston on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 734th most-seen of the 1057 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Banded Hickory Borer in Houston on a given day, so our monthly data shows no clear season.
4th of 4
Of the 4 cities where we can rate Banded Hickory Borer sightings, Houston ranks 4th at under 5%. The best odds are in Austin (United States, about 10%), San Antonio (United States, under 5%) and Dallas (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Banded Hickory Borer is recorded against all the insects logged in Houston (9 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.
