Disonycha discoidea
In 3 days ~10%
Disonycha discoidea, the passionflower flea beetle, is a species of flea beetle in the family Chrysomelidae. It is found in North America. The adult is large for a flea beetle, roughly 7 mm long and 4 mm wide. The body is oval-shaped and orange-red (some references base the description on preserved specimens, which yellow with age). The antennae are dark, with the basal and apical joints sometimes paler.
Two subspecies are recognized, distinguished by elytra coloration: D. discoidea discoidea: elytra with a black discoidal spot of variable but large size, not reaching the margins. D. discoidea abbreviata: elytra with alternating longitudinal black and pale yellow stripes.
Chevrolat coined the genus name Disonycha from the Greek roots δίς (two) and ὄνυξ (claw). The specific epithet discoidea presumably refers to the disc-shaped black spot on the elytra. Disonycha discoidea is found in the eastern United States, from Texas and Kansas in the west to Georgia and Maryland in the east. Some references report a broader range of Colorado to Florida to Rhode Island.
As the common name suggests, Disonycha discoidea is a Passiflora... Wikipedia →

Rare
Under 5% of wildlife watchers report a Passionflower Flea Beetle sighting in Dallas on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1307th most-seen of the 1412 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 Passionflower Flea Beetle in Dallas on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Passionflower Flea Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Dallas, in our data
Dallas is the only city on Wallace's Line with enough records to rate Passionflower Flea 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 Passionflower Flea Beetle is recorded against all the insects logged in Dallas (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.
