Ormyrus nitidulus is a species of parasitoid wasp in the family Ormyridae. It is primarily associated with oak gall wasps. Ormyrus nitidulus is a small metallic wasp with an approximate adult length of around 5mm. It has a fairly widespread distribution, being found across the Palaearctic.
Per the Universal Chalcidoidea Database, O. nitidulus is found across Western Palaearctic realm, from the north-west in the United Kingdom to Algeria in the south, and as far east as Iran. Ormyrus nitidulus larvae are idiobiont ectoparasitoids primarily associated with oak gall wasps, including but not limited to species in the genera Andricus, Cynips, and Biorhiza. The species is stated to be less polyphagous than the related Ormyrus pomaceus which utlizes a wider range of host oak gall wasps.
Species in the genus Ormyrus are generally characterised by bright metallic colours, the coarsely crenulated sculpture of the metasoma, well-developed hind coxae, short stigmal veins and two stout and curved metatibial spurs.
O. nitidulus can be distinguished from the other oak gall wasp-parasitizing members of the genus in the palaearctic... Wikipedia →

Rare
Under 5% of wildlife watchers report an Ormyrus nitidulus sighting in London on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1059th most-seen of the 1504 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.
September
In that month about 10% of wildlife watchers report an Ormyrus nitidulus in London on a given day, against under 5% in October to August, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Ormyrus nitidulus sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Hymenoptera
The closest relatives of the Ormyrus nitidulus that you can see in London (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Common Carder Bumble Bee (about 40%), Buff-Tailed Bumble Bee (about 30%) and Hairy-Footed Flower Bee (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ormyrus nitidulus is recorded against all the insects logged in London (11 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.
