Orsillus depressus is a species of seed bug in the family Lygaeidae. It is a terrestrial insect native to southern Europe. It is considered a naturalized introduced species in the UK. O. depressus was first recorded in England in the 1980s and is now common throughout central and southern England. In southern Europe, its host plants are trees in Cupressaceae while in the UK Lawson's cypress is the most common host plant. O. depressus is approximately 6 mm in length and has a browny-orange coloration.

Rare
Under 5% of wildlife watchers report an Orsillus depressus sighting in London on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1109th 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.
December and January
In those months about 10% of wildlife watchers report an Orsillus depressus in London on a given day, against under 5% in February to November, the lowest months.
5th of 5
Of the 5 cities where we can rate Orsillus depressus sightings, London ranks 5th at under 5%. The best odds are in Prague (Czechia, about 10%), Warsaw (Poland, under 5%) and Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Orsillus depressus is recorded against all the insects logged in London (9 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.
