Aphids – Otherwise know as greenfly and black fly these sap-sucking insect pests feed on all foliage and flowers and are particularly partial to ornamental plants, fruit, vegetables and houseplants. There are over 500 species of Aphid in Britain and they range in size from 1-7mm (1/16 – 1/4in) long.

Aphids cause distorted growth and excrete a sticky substance which attracts a growth of sooty mould. They can be carried for hundreds of miles by wind or air currents and can transfer viruses to other plants notably Strawberries, Raspberries, Tomatoes, Dahlias and Sweet peas.

They are commonly found on roses and can build up into big colonies if you let them!
