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 Austin on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 781st most-seen of the 1624 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 Austin on a given day, against under 5% in May to March, the lowest months.
Yes
Of the 2 cities where we can rate Golden-Headed Weevil sightings, Austin has the highest daily chance: under 5%. Next come Houston (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 Austin (24 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.
