Eucera longicornis is a species of bee in the family Apidae, subfamily Apinae, and tribe Eucerini, the long-horned bees.

In the male, the clypeus and labrum are yellow, and the antennae are very long, being as long as the head and body combined. The female's antennae are shorter.
This bee occurs in the Palearctic realm, ranging from Western Europe to as far east as Siberia and China. In Britain it is patchily distributed in southern England and Wales. In favoured locations it can be quite numerous and tends to nest in aggregations. It typically is present near the coast in bare areas and short turf, in open grassy areas in woodland and sometimes on heathlands.
The adult female prepares a burrow, usually in clay soil, kneading the walls to make them smooth. The nest is provisioned with a mixture of pollen and honey made into a paste and an egg is laid on this. The larva feeds on the paste when it hatches. The winter is usually... Wikipedia →

Rare
Under 5% of wildlife watchers report a European Longhorn sighting in Moscow on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 637th most-seen of the 1111 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 European Longhorn in Moscow on a given day, so our monthly data shows no clear season.
Only Moscow, in our data
Moscow is the only city on Wallace's Line with enough records to rate European Longhorn sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Apidae
The closest relatives of the European Longhorn that you can see in Moscow (family Apidae, Honey Bees, Bumble Bees, and Allies) are Common Carder Bumble Bee (about 10%), Tree Bumble Bee (about 10%) and Red-Tailed Bumble Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Longhorn is recorded against all the insects logged in Moscow (13 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.
