Which one do I have?
- Black bean aphidAphis fabaeThe usual answer to "black aphids": matt black colonies packed onto bean tips, poppies and nasturtiums in early summer. Damaging on broad beans, mostly tolerable elsewhere.Beans · Bedding plants · Cut flowers · Carrots & root veg · Evergreens & shrubs
- Cabbage aphidBrevicoryne brassicaeA grey-green aphid dusted with white wax, found only on brassicas, where it forms dense ash-grey colonies under the leaves and in growing points, heads and Brussels sprouts. It thrives in cool weather, so autumn crops suffer most. The wax makes colonies hard to wet with sprays.Brassicas
