Brassicogethes aeneus
In 3 days ~10% in a week ~20%
Brassicogethes aeneus, the common pollen beetle, is a species of pollen beetle in the family Nitidulidae. Other common names include the rape pollen beetle and rape blossom beetle. It was previously known as Meligethes aeneus.
It is found in Europe and Northern Asia (excluding China) and North America. A subspecies of Brassicogethes aeneus is B. aeneus dauricus. Adults are about 2–3 mm long, 1–2 mm wide and black with a hint of metallic green. The larvae are up to 3 mm long and white with brown sclerotised plates.
Brassicogethes aeneus is an important pest of oilseed rape. It is not known whether it contributes to the pollination of the crop. The female beetle lays its eggs in the flower buds of the host-plant and the larvae develop within the flowers. Oviposition and feeding damage the buds of oilseed rape and similar Brassicas and may cause the flowers to drop. Both adults and larvae feed on the pollen and nectar in the flowers. Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Pollen Beetle sighting in London on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1394th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Common Pollen Beetle in London on a given day, so our monthly data shows no clear season.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Common Pollen Beetle sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Common Pollen Beetle is recorded against all the insects logged in London (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.
