Aphids
It is usually possible to see aphid colonies with the naked eye, many species colonise shoot tips, flower buds and the underside of younger leaves
Aphids can cause stunted growth with curled or distorted leaves and can weaken the plant
Many aphids excrete a sticky honeydew on which black sooty moulds can grow
These look like black or brown powder on upper leaf surfaces. They grow on sugar-rich honeydew produced by sap-sucking insects, or occasionally on sugary substances produced by the plant itself. In most cases, sooty mould is a tell-tale sign of an insect infestation.
White cast skins of aphids can accumulate on the upper surface of leaves
Ants may be found climbing plants with aphid colonies, they tend the aphids obtaining honeydew as a reward. The ants will remove aphid predators
