Compsus auricephalus, the golden-headed weevil, is a species of broad-nosed weevil in the beetle family Curculionidae. It is native and fairly widespread across the southern U.S.A., extending through Central America in Guatemala and Mexico.
There are two color morphs of Compsus auricephalus: predominantly green with pink/coppery head and part of the legs, or completely white to pale brown. The status, variation, distribution, and biological information about the species was revised in 2020.
The species was originally described by Thomas Say in 1824 under the name Curculio auricephalus on page 310. It belongs to the predominantly Neotropical genus Compsus in the tribe Eustylini, in the subfamily Entiminae. It is the northernmost distributed species of the genus and the only native representative of the genus in the U.S.A.
There is an additional species distributed in Costa Rica, Honduras, Nicaragua, and Panama (as far south as the Canal Zone) that partly matches the white morph of Compsus auricephalus. Its more elevated elytral intervals and features of the male genitalia confirm that it is a different species, although it is still unknown if this species has an existing... Wikipedia →

Rare
Under 5% of wildlife watchers report a Golden-Headed Weevil sighting in Houston on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 370th 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.
April
In that month about 10% of wildlife watchers report a Golden-Headed Weevil in Houston on a given day, against under 5% in May to March, the lowest months.
Among the best
Of the 2 cities where we can rate Golden-Headed Weevil 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 Golden-Headed Weevil is recorded against all the insects logged in Houston (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.
