Languria angustata, the eastern black-headed lizard beetle is a North American species of pleasing fungus beetle (family Erotylidae). It belongs to the lizard beetle tribe (Languriini) of subfamily Languriinae; formerly, their subfamily was considered a distinct family, and their tribe upranked to subfamily status, whereas some recent authors prefer to merge Languriinae into subfamily Erotylinae.
This beetle is only found in North America, where it is usually encountered from March to October. It occurs from Ontario in Canada to Iowa in the USA, and in the south from northern Florida to eastern Texas. Most records are from the northeast of its range.
This is a smallish beetle even by the standards of its family, with adults being 6-9 mm long. It is mostly blackish overall on the upperside, with a red pronotum that in some individuals has a somewhat indistinct black spot. The underside is also mostly red, but the head, the last two segments of the abdomen and usually also the metasternum are blackish. The femora of the forelegs are black with red bases, and those of the mid- and hindlegs are red with black tips; the tibiae are all red, and the tarsi all blackish. The... Wikipedia →

Rare
Under 5% of wildlife watchers report a Languria angustata sighting in Shenandoah National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 630th most-seen of the 723 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and June
In those months about 10% of wildlife watchers report a Languria angustata in Shenandoah National Park on a given day, against under 5% in May and July–March, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Languria angustata sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Shenandoah National Park, in our data
Shenandoah National Park is the only park on Wallace's Line with enough records to rate Languria angustata sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Languria angustata is recorded against all the insects logged in Shenandoah National Park (5 verified sightings from 2019 to 2026), 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.
