Aphids are the bane of gardeners and farmers alike. Settling in vast numbers on the soft green plant tissue, sucking the sap, and life, out of the plant. If that wasn't bad enough they are also major carriers of plant viruses. However, they are not all bad as many species of ant 'milk' them like cows for their honeydew. Aphids are a large family of small insects, containing many thousands of species. Some particularly infamous ones are the black bean aphid, rose aphid and the green peach aphid. Luckily help is in hand in the form of beetles who love to feast on this bounty.
Scientific name: Aphididae
There is a natural biological control between predators and prey in the insect world.
Aphids are breeding machines reproducing over a billion descendants each, but other insects such as ladybirds and spiders can control these numbers.
Ants tend aphids like a shepherd tends his sheep.
David Attenborough looks at aphids and their relationship with ants in a garden. The ants protect the aphids from a predatory ladybird.
