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.

GBIF citizen-science records
It is estimated from how often the Parent Bug is recorded against all the insects logged in Helsinki (76 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.
