Ceropales maculata was first formally described as Evania maculata in 1775 by the Danish zoologist Johan Christian Fabricius with its type locality given as England. This species is now classified in the genus Ceropales which is one of two genera in the subfamily Ceropalinae within the spider wasp family Pompilidae.
Cerpales maculata is a small spider wasp. Females are 6-9 mm in length, and males are 5-7.5 mm. There are distinct with bold white markings on its black body. The legs are orange-red, with the hind legs being very long. In a British context the absence of a red band on the abdomen identifies this species from C. variegata.

Rare
Under 5% of wildlife watchers report a Ceropales maculata sighting in Boston on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1063rd most-seen of the 1200 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Ceropales maculata in Boston on a given day, so our monthly data shows no clear season.
Only Boston, in our data
Boston is the only city on Wallace's Line with enough records to rate Ceropales maculata sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Hymenoptera
The closest relatives of the Ceropales maculata that you can see in Boston (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Common Eastern Bumble Bee (about 50%), Brown-Belted Bumble Bee (about 30%) and Eastern Carpenter Bee (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ceropales maculata is recorded against all the insects logged in Boston (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.
