In 3 days ~10% in a week ~20%
Calliphora vomitoria, known as the bluebottle fly, orange-bearded bluebottle, or bottlebee, is a species of blowfly, a species in the family Calliphoridae. Calliphora vomitoria is the type species of the genus Calliphora. It is common throughout many continents including Europe, Americas, and Africa. They are fairly large flies, nearly twice the size of the housefly, with a metallic blue abdomen and long orange setae on the gena.
While adult flies feed on nectar, females deposit their eggs on rotting corpses, making them important forensic insects, as their eggs and timing of oviposition can be used to estimate time of death. Bluebottle flies are typically 10–14 mm (3⁄8–9⁄16 in) long, almost twice the size of a housefly. The head and thorax are dull gray, and the back of the head has long yellow-orange setae. The abdomen is bright metallic blue with black markings. Its body and legs are covered with black bristly hairs. It has short, aristate antennae and four tarsi per leg. The eyes are red and the wings are transparent. The legs and antennae are black and pink. The chest is bright purple and has spikes for protection from other flies. To differentiate C. vomitoria...

Rare
Under 5% of wildlife watchers report an Orange-Bearded Bluebottle Fly sighting in Paris on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 519th most-seen of the 916 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.
March and April
In those months about 10% of wildlife watchers report an Orange-Bearded Bluebottle Fly in Paris on a given day, against under 5% in May to February, the lowest months.
Yes
Of the 2 cities where we can rate Orange-Bearded Bluebottle Fly sightings, Paris has the highest daily chance: under 5%. Next come London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Orange-Bearded Bluebottle Fly is recorded against all the insects logged in Paris (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.
