Dolycoris baccarum, the sloe bug or hairy shieldbug, is a species of shield bug in the family Pentatomidae. This species is widespread in most of Europe and Central Asia. These shield bugs mainly inhabit hedgerows and woodland edges, fields, forests, parks and gardens.
Dolycoris baccarum can reach a length of about 10–12.5 millimetres (0.39–0.49 in). The basic color of pronotum and elytra is quite variable, but usually it is reddish purple, while scutellum is ocher. During the winter the basic color is dull brown. The whole body is quite hairy. The antennae are made by 4-5 black and white sections and the margins of the abdomen (connexivum) are alternately mottled with whitish and black. The male and female are very similar. A related species encountered in Europe is Dolycoris numidicus.
It is univoltine in the northern part of the range and bivoltine in the warmer southern areas. Adults of these shield bugs can be found all year around, as they overwinter. They emerge in the following spring, when they mate and females lay eggs. By the end of summer the new generation of adults appear. Nymphs feed on many plants, especially... Wikipedia →

With luck
About 10% of wildlife watchers report a Sloe Bug sighting in Beijing on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 85th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April, June–August and October–November
In those months about 10% of wildlife watchers report a Sloe Bug in Beijing on a given day, against under 5% in May, September and December–March, the lowest months. Those are among Beijing's wettest months, with about 70 mm of rain a month against almost none in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Sloe 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.
35th of 53
Of the 53 cities where we can rate Sloe Bug sightings, Beijing ranks 35th at about 10%. The best odds are in Izmir (Turkey, about 30%), Birmingham (United Kingdom, about 20%) and Helsinki (Finland, about 20%).
Same family: Pentatomidae
The closest relatives of the Sloe Bug that you can see in Beijing (family Pentatomidae, Stink Bugs) are Brown Marmorated Stink Bug (about 10%), Yellow-Spotted Stink Bug (about 10%) and Painted Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sloe Bug is recorded against all the insects logged in Beijing (35 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.
