I know you’ll be so excited to receive yet ANOTHER email asking…do you know what kind of bug this is? I live in San Antonio, TX and have found these bugs in my garden just in the last couple of weeks. I can’t quite tell if they’re damaging my plants or not, but they are everywhere and multiplying rapidly. I really appreciate your help!
Your photo is rather blurry, but we are almost certain you have Harlequin Bug nymphs, Murgantia histrionica. This is a type of Stink Bug that often infests cabbage plants and wild mustard. They can get very plentiful.
