Answer: Everywhere, as on all your plants? If so, then they are likely aphids which are small soft-bodied, sucking insects. They come in a variety of colors, including orange and usually congregate in groups. They can simply be washed off plants with a jet of water from a hose. Doing this for a few consecutive days usually eliminates the problem. Soap sprays are also effective. If they have already done damage to the plant by their sucking, then prune the infested part and enclose in a plastic bag to eliminate the destructive insects. Lady bugs have voracious appetites for aphids so don't use chemical sprays which will also harm the beneficial lady bugs!
