Gonocerus acuteangulatus is a herbivorous species of true bug in the family Coreidae. It is commonly known as the box bug in the UK as it once only occurred in Box Hill in Surrey where it fed on box trees. This species was formally described by the German zoologist Johann Goeze in 1778, under the name Cimex acuteangulatus.
This species commonly occurs throughout the Mediterranean region and extends to Central Asia and parts of northwestern Europe. These heat-loving bugs inhabit mainly dry and warm, south-exposed environments, bushes and forest edges with shrubs that bear berries and small trees of various families, especially Buxaceae and Rhamnaceae, as well as Rosa canina and Crataegus species (Rosaceae) or Lonicera xylosteum (Caprifoliaceae).
Gonocerus acuteangulatus is a medium-sized insect, between 11 and 14 mm long as an adult. These bugs are speckled reddish-brown with a slightly expanded abdomen. The nymphs have a green abdomen. This species is rather similar to Coreus marginatus, but it shows a narrower abdomen and has sharper lateral margins of the pronotum (hence the Latin species name acuteangulatus).... Wikipedia →

With luck
About 10% of wildlife watchers report a Box Bug sighting in Lyon on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 54th most-seen of the 411 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March to June
In those months about 20% of wildlife watchers report a Box Bug in Lyon on a given day, against under 5% in October to December, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Box Bug sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Box Bug is recorded against all the insects logged in Lyon (41 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.
