I found some bugs on my zinnias. At first I thought they were squash bug eggs but once they moved and I noticed the legs I realized they were nymphs of some bug. I attached a picture. The bugs are about 1/16th of an inch. Quite small. Like flea beetle size. It appears there is another cluster of eggs in the picture. Any idea what they are?

The red insects are four-Lined Plant Bug nymphs, Poecilocapsus. Adults are greenish-yellow with four black strips running longitudinally down the wings. The feeding by both adults and nymphs may cause stippling on leaves—spots of discoloration that may turn from yellow to brown to black. Horticultural oil will kill nymphs.

After reviewing my answer we now think that the insects may be stink bugs nymphs. We do not know the species. They have piercing mouth parts.
