Acanthocephala terminalis is a species of leaf-footed bug in the family Coreidae. It is found in the eastern half of the United States and eastern Mexico. It is harmless to humans and pets and does not bite or sting and there is no evidence that it carries parasites or human diseases; however, it may release a foul odor if threatened or squashed.
Acanthocephala terminalis is usually around 18–25 millimetres (0.71–0.98 in) long with a dark gray to black color. The fourth (and last) segment of their antennae have orange coloration, and the tibia of their hind legs have a flat, leaf-like appearance. Sexual dimorphism is relatively limited. The hind femora and shape of the expanded hind tibia may differ slightly in shape, while body size remains relatively constant.
Acanthocephala terminalis is usually found in the eastern half of the United States and parts of southeast Canada. They will usually live in woodlands, fields, and meadows. Acanthocephala terminalis will begin its mating period in late spring, and females will lay eggs on host plants. Once the juveniles hatch they will molt five times before they reach adulthood...

Rare
Under 5% of wildlife watchers report an Acanthocephala terminalis sighting in Philadelphia on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 227th most-seen of the 632 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.
May and July
In those months about 10% of wildlife watchers report an Acanthocephala terminalis in Philadelphia on a given day, against under 5% in June and August–April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Acanthocephala terminalis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 14
Of the 14 cities where we can rate Acanthocephala terminalis sightings, Philadelphia ranks 11th at under 5%. The best odds are in Dallas (United States, about 10%), Austin (United States, about 10%) and Boston (United States, about 10%).
Same family: Coreidae
The closest relatives of the Acanthocephala terminalis that you can see in Philadelphia (family Coreidae, Leaf-footed Bugs) are Leptoglossus oppositus (about 10%) and Western Conifer Seed Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Acanthocephala terminalis is recorded against all the insects logged in Philadelphia (22 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.
