Proxys punctulatus, the black stink bug, is a species of stink bug in the family Pentatomidae. It is found in the Caribbean Sea, Central America, and North America. The adult of P. punctulatus is 11-13 mm long and has a mostly black body with a yellow spot at the apex of the scutellum. There are six legs which are black and cream in colour. The head as well as the humeral angles of the pronotum are pointed.
The life cycle of this species has been studied in Union County, Illinois. Adults overwinter in leaf litter near their host plants. They become active in June and reproduce. Eggs are usually laid singly. These eggs hatch into nymphs which go through five instars. A laboratory experiment, rearing P. punctulatus on Tradescantia subaspera under constant temperature and light, found that on average egg incubation takes 9.04 days while the five nymphal instars take 5.06, 7.15, 7.56, 9.32, and 15.93 days.
Proxys punctulatus is omnivorous, feeding on both plant juices and on insect larvae. It has been found on blackberry, spiderwort, cotton, soybean and citrus plants. Feeding results in disfigured leaves and discolored areas on stems, but this... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black Stink Bug sighting in Washington on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 627th most-seen of the 1807 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black Stink Bug in Washington on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black Stink 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.
7th of 9
Of the 9 cities where we can rate Black Stink Bug sightings, Washington ranks 7th at under 5%. The best odds are in San Pedro Sula (Honduras, about 10%), Orlando (United States, about 10%) and Dallas (United States, under 5%).
Same family: Pentatomidae
The closest relatives of the Black Stink Bug that you can see in Washington (family Pentatomidae, Stink Bugs) are Brown Marmorated Stink Bug (about 10%), Florida Predatory Stink Bug (about 10%) and Green Stink Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Stink Bug is recorded against all the insects logged in Washington (30 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.
