Elasmucha grisea, common name parent bug, is a species of shield bugs or stink bugs belonging to the family Acanthosomatidae. The term parent bugs includes also the other species of the genus Elasmucha and some species of the family Acanthosomatidae.
Elasmucha grisea can reach a length of 6.5–8.8 millimetres (0.26–0.35 in). Males are smaller than females. These medium-sized shield bugs are usually brown-reddish, but there are also gray (hence the Latin species name grisea) and green-brown specimens. The connexiva are black and white. The upper side is covered with several dark dots. The scutellum usually shows an evident black patch. The ventral face is largely punctuated with black. The lateral corners of the pronotum are simply beveled. The front corners of the pronotum show a more pronounced tooth. Antennae are blackish in the male, dark brown in the female.

Rare
Under 5% of wildlife watchers report a Parent Bug sighting in Pyrénées National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 610th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and September–October
In those months about 10% of wildlife watchers report a Parent Bug in Pyrénées National Park on a given day, against under 5% in August and November–June, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Parent Bug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate Parent Bug sightings, Pyrénées National Park ranks 4th at under 5%. The best odds are in Aigüestortes National Park (Spain, about 10%), Ecrins National Park (France, about 10%) and Bavarian Forest National Park (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Parent Bug is recorded against all the insects logged in Pyrénées National Park (13 verified sightings from 2019 to 2026), 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.
