Belonocnema treatae
In 3 days ~10%
Belonocnema treatae is a species of gall wasp that forms galls on Quercus virginiana and very rarely Quercus geminata. There are both asexual and sexual generations. The asexual generation forms galls on the underside of leaves while the sexual generation form galls on the roots. This species can be found in the United States, where it is known from Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina. It, along with the other described Belonocnema species, has been used to study speciation.
Belonocnema treatae was first described in 1881 by Gustav Mayr on the basis of sexual generation adults collected by noted naturalist Mary Treat. She collected the galls in Green Clove Spring, Florida, from root galls growing on Quercus virginiana. Belonocnema treatae was named in honor of her by Mayr. Due to a printing error, the genus first appeared as Belenocnema until it was subsequently corrected.
Later that same year, William Harris Ashmead described individuals from the same galls as Dryorhizoxenus floridanus, but later synonymized this name under Mayr's B. treatae in 1886. Genetic data places B. treatae as sister to B. fossoria.

Rare
Under 5% of wildlife watchers report a Belonocnema treatae sighting in Miami on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 752nd most-seen of the 826 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 Belonocnema treatae in Miami on a given day, so our monthly data shows no clear season.
Only Miami, in our data
Miami is the only city on Wallace's Line with enough records to rate Belonocnema treatae sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Belonocnema treatae is recorded against all the insects logged in Miami (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.
