I’d thought they were butterfly eggs, but obviously not. What are these things, do you know? and will they hurt my basil and pepper plants?
THANKS!!

Brown Marmorated Stink Bug Hatchlings

Hi Kathy,
These are newly hatched Harlequin Stink Bugs,
Murgantia histrionica.  We verified their identity by matching them to a photo on BugGuide.  According to BugGuide:  “Sucks on juices of plants in the mustard/cabbage family (Brassicaceae). Can be a very serious crop pest.” Basil and pepper and not in the family Brassicaceae, but if the eggs were laid on those plants, it is possible that they may also provide a food source.  Stink Bugs have piercing/sucking mouthparts, and they feed on the fluids of the plants.  If the Harlequin Stink Bugs are particularly plentiful, they may cause irreparable damage to young and sensitive plants.

Cool. Thanks very much for the response.

    Not harlequin bug. Their eggs are marked with dark bands.

    Instead, they’re the recent nasty immigrant, BMSB; aka brown marmorated stink bug!

    Destroy as soon as seen.
