What are the small insects that group together and leave a sticky sugary substance on my plants, car or sidewalks?
These insects are aphids. They are commonly found on trees, shrubs and flowers. Aphids come in many different colours such as green, yellow, brown, pink or black and sizes. They are soft-bodied insects that suck the sap from the plant leaves or roots. Aphids excrete a sugary substance called honeydew on the leaves which overtime can cause sooty mold. In most cases aphids are found in the folded over part of leaves, known as a clutch. This is where the eggs and the next generation of new nymphs are present.
