Odontocynips nebulosa
In 3 days ~10% in a week ~20%
Odontocynips nebulosa is a species of cynipid wasp that induces large, woody, subterranean galls on the roots of oaks. For many years, this species was incorrectly associated with a common, mealy-white gall found on oak leaves; however, that gall is now known to be induced by a different, undescribed species.
The adult wasp is small and rarely observed. The galls are the most common sign of its presence. They form on the roots of young oak shoots, sometimes 5–10 cm underground. Single galls are globular and 10–13 mm in diameter, but they are often aggregated into irregular, lobed, polythalamous (many-chambered) masses that can be as large as 8 cm in diameter. When fresh, they are covered with smooth, light-colored bark similar to the host root, and they become hard and woody when dry. The internal larval cavities are 6–8 mm in diameter.
The wasp is found across the southeastern and central United States, with its range extending from Florida to Texas and north to Missouri and Arkansas. This species is found on the tangled roots of young oak shoots growing in dense thickets where humus has accumulated.

Rare
Under 5% of wildlife watchers report an Odontocynips nebulosa sighting in Austin on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 721st 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.
February and March
In those months about 10% of wildlife watchers report an Odontocynips nebulosa in Austin on a given day, against under 5% in April to January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Odontocynips nebulosa sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Austin, in our data
Austin is the only city on Wallace's Line with enough records to rate Odontocynips nebulosa sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cynipidae
The closest relatives of the Odontocynips nebulosa that you can see in Austin (family Cynipidae, Gall Wasps) are Belonocnema kinseyi (about 10%), Druon quercuslanigerum (about 10%) and Leafy Oak Gall Wasp (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Odontocynips nebulosa is recorded against all the insects logged in Austin (26 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.
