It is on average 3.7–5 mm (0.15–0.20 in) long and is found from North America (particularly in Minnesota, Florida, and Texas) to Panama. It breeds in acorns and its larvae are found within them and use them as food. C. posticatus has had a growing presence within oak trees, which they attack by destroying seeds within the tree.Their activity in relation to oak trees and forest ecosystems is not yet fully understood.
Conotrachelus posticatus is prevalent throughout the regions of North America, especially from Minnesota to Texas, and can be found as south as Panama. The head is described as being "densely punctate". It has a long "nose" that bears some resemblance to the trunk of an elephant. The nose has a chewing mouth piece at its end, allowing for it to process food. C. posticatus is brown and/or black in color. In its adult stage the color is described as a "dark reddish-brown."

Rare
Under 5% of wildlife watchers report an Oak Curculio sighting in Houston on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 790th 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 an Oak Curculio in Houston on a given day, so our monthly data shows no clear season.
Among the best
Of the 3 cities where we can rate Oak Curculio sightings, Houston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Oak Curculio 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.
