Hi Bugman
I have been an insect enthusiast since childhood and this is the first time I’ve seen harlequin bugs in our area (Lancaster PA). I read on bug that Pennsylvania is the northern part of their range.
There were around 50 individuals, nymphs and adults, on a cocklebur plant at my garden near Mastersonville, PA. Thought you could use some more photos of them since I only found once incidence of these insects on your site.

Hi Melody,
Thank you so much for sending us your photos of Harlequin Stink Bugs.  We are especially intrigued that you found them feeding on cocklebur.  According to the UC Davis Statewide Integrated Pest Management Program, cocklebur,
Xanthium strumarium, is in the sunflower family Asteraceae, and we have always associated the Harlequin Stink Bug with plants in the cabbage family Brassicaceae.  According to BugGuide, Harlequin Stink Bugs feed on:  “primarily Brassicaceae (horseradish, cabbage, cauliflower, collards, mustard, Brussels sprouts, turnip, kohlrabi, radish); may also attack tomato, potato, eggplant, okra, bean, asparagus, beet, weeds, fruit trees and field crops.”  Searching our site with the internal search engine and the scientific name Murgantia histrionica, we found over ten postings buried in our archives.
