In 3 days ~10%
Gnamptopelta obsidianator is a species of wasp in the family Ichneumonidae and the only species in the monotypic genus Gnamptopelta. The genus name Gnamptopelta is derived from the Greek γναμπτός (gnamptós) meaning 'bent' or 'curved' plus the Greek πέλτη (péltē) meaning 'shield'. This refers to the concave shape of the clypeus found in this genus.
Gnamptopelta obsidianator can be distinguished from allied genera by the concave structure of the clypeus. They are large wasps with a body length of 20 to 23 millimetres (13⁄16 to 7⁄8 in). The scutellum is high and conical. Typically, the body is almost entirely black, including the wings, except for the fore and mid legs, of which the tibiae and tarsi are yellowish-brown. In some specimens, the orbits may be yellow. The antennae are orange-yellow, sometimes with the tips blackish. Specimens from the southern extent of the species' range may have parts of the head and thorax more or less ferruginous.
This species is very similar in appearance to Conocalma brullei but can be distinguished by the lack of an elevated structure on the petiole of the abdomen and by the shape of the clypeus.... Wikipedia →

Under 5% of wildlife watchers report a Bent-Shielded Besieger Wasp sighting in Chicago on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 814th most-seen of the 978 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 Bent-Shielded Besieger Wasp in Chicago on a given day, so our monthly data shows no clear season.
Among the best
Of the 5 cities where we can rate Bent-Shielded Besieger Wasp sightings, Chicago ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Boston (United States, under 5%), Montreal (Canada, under 5%) and New York City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Bent-Shielded Besieger Wasp is recorded against all the insects logged in Chicago (6 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.
