Hemipenthes morio is a species of bee fly belonging to the family Bombyliidae subfamily Anthracinae. This common bee-fly is mainly present in most of Europe, the eastern Palearctic realm, and the Near East. It is extremely similar to H. morioides, a species found in North America which was previously considered to be the same species as H. morio.
The adults grow up to 7–10 millimetres (0.28–0.39 in) long, while the wingspan reaches 5–15 millimetres (0.20–0.59 in). They can mostly be encountered from May through August feeding on nectar and pollen of a variety of flowers (for instance of Lavandula stoechas, Cytisus scoparius, Thapsia villosa, etc.).
Their body is dark-brown and hairy, especially on the side of the abdomen. The wings have a light area located near the apex and a dark area close to costal margin, separated by a zig-zag division. The apex of cell R1 is hyaline. The dark area of the wings almost reaches the end of the abdomen.
The larvae are hyperparasites (parasites of parasites), mainly developing in larvae of flies (Diptera, Tachinidae), as well as in wasp larvae (Hymenoptera, Ichneumonidae) parasitizing caterpillars moths (Noctuidae). Wikipedia →

Rare
Under 5% of wildlife watchers report a Black Banded Bee Fly sighting in Copenhagen on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 424th most-seen of the 476 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.
June
In that month about 10% of wildlife watchers report a Black Banded Bee Fly in Copenhagen on a given day, against under 5% in July to May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Black Banded Bee Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 18
Of the 18 cities where we can rate Black Banded Bee Fly sightings, Copenhagen ranks 18th at under 5%. The best odds are in Kyiv (Ukraine, about 20%), Kharkiv (Ukraine, about 20%) and Warsaw (Poland, about 20%).
Same family: Bombyliidae
The closest relatives of the Black Banded Bee Fly that you can see in Copenhagen (family Bombyliidae, Bee Flies) are Greater Bee Fly (about 10%) and Anthracite Bee-Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Banded Bee Fly is recorded against all the insects logged in Copenhagen (7 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.
