Thanks so much for reaching out UVM AskExtension. The bug on your snaps is called a Twice-Stabbed Stink Bug/Harlequin bug (Cosmopepla lintneriana). Our entomologist offers this response:
These harlequin bugs are difficult to manage. Learning how to identify the eggs is a start and then removing them before they hatch. Once they hatch you can hand pick them if there aren’t too many infected plants. The standard organic pesticides, such as neem-based products, are effective, but they also impact the other natural enemies. Here’s a few websites that provide additional information about managing harlequin bugs in general and identification of this species in particular:
I hope this information helps! Thanks again for reaching out to AskExtension at UVM and good luck!
