Stenoria analis, the ivy bee blister beetle, is a species of blister beetle from the family Meloidae which is found in western Europe and North Africa and is a specialist cleptoparasite of the ivy bee (Colletes hederae) larvae. Its occurrence in regions outside of the known range of the ivy bee, for example in North Africa, suggest that it has other hosts.
Stenoria analis is a small beetle which is coloured black and buff. These beetles fly in sunny weather with a swift flight which resembles that of bees and wasps. Stenoria analis is a species ranging from southern Europe and North Africa as far north as southern Germany and the Channel island of Jersey, and as far east as Silesia in Poland in the north, and southern Russia and Anatolia in the south. In western Europe the only known host for S. analis was Colletes hederae, which does not occur in areas such as North Africa or Anatolia, so it was postulated that there were hosts other than Colletes hederae. Larvae were recorded from males of Colletes succintus in France. As Colletes hederae spreads north in western Europe S. analis has followed, and has been recorded from new areas in Germany;...

Rare
Under 5% of wildlife watchers report a Stenoria analis sighting in Paris on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 686th 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.
August
In that month about 10% of wildlife watchers report a Stenoria analis in Paris on a given day, against under 5% in September to July, the lowest months.
Only Paris, in our data
Paris is the only city on Wallace's Line with enough records to rate Stenoria analis sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Stenoria analis is recorded against all the insects logged in Paris (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.
