Squash/stink bugs. They are worse than the beetles. Either squish them, if you can catch them, or spray the bugs with Spinosad Soap. Look on the underside of the leaves for the eggs and either squish them or spray them with Neem Oil. The eggs will be tightly close together and about 20-50 in a group. Keep a close watch for the baby bugs. They look a lot like giant aphids, usually gray with red legs. Use the spinosad on them.
