I picked as many as I could off and did some tests in a cup neem oil killed them on contact it seems that the eggs were empty so I'm guessing that those guys came from them thanks for the ID
Those are definitely stankers. Keep an eye on the situation. When there's one clutch of eggs and nymphs, others are likely to follow.
I harbor an irrational hatred for stankbugs. They aren't particularly difficult to eradicate, & there are far more destructive pests, but something about their whole stanky lifestyle just irks me on a primal level.
Nasty little things come to think of it I saw a fully grown one the other day on this plant. I picked it off and it sprayed that nasty stuff. Gross little creatures I'm goin to be inspecting all my plants for eggs just to be sure.
