Tritoma biguttata, the two-spotted pleasing fungus beetle or two-spotted tritoma, is a North American species of small pleasing fungus beetle (family Erotylidae). It belongs to subfamily Tritominae, or – in taxonomic arrangements that prefer a more comprehensive subfamily Erotylinae – in tribe Tritomini of the Erotylinae.
This is a tiny beetle, about 2.7-4.4 mm long and 1.5-2.6 mm wide as adults, widely oval in shape with somewhat pointed wingtips, and a shiny surface of the exoskeleton. As typical for Tritoma sensu stricto, T.biguttata has a triangular mentum, as well as an epistome whose tip is sharply cut off, causing the line running parallel to the epistome margin to angle towards the antennae insertions.
Their coloration differs according to subspecies: Typical adults of the nominate T.b.biguttata are black on the top of the head, the upperside of the pronotum and the underside of the pronotal epipleura, the scutellum, and most of the elytra. The "clubs" of the antennae are dark reddish-brown. The rest of head and underside, the legs, and the "stalk" of the antennae are orange. On each elytron, there is a large and somewhat triangular orange-red spot, extending... Wikipedia →

Rare
Under 5% of wildlife watchers report a Two-Spotted Pleasing Fungus Beetle sighting in New York City on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1492nd most-seen of the 1623 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Two-Spotted Pleasing Fungus Beetle in New York City on a given day, so our monthly data shows no clear season.
Only New York City, in our data
New York City is the only city on Wallace's Line with enough records to rate Two-Spotted Pleasing Fungus Beetle sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Two-Spotted Pleasing Fungus Beetle is recorded against all the insects logged in New York City (5 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.
