Aphids

These rose aphids seemed to be intent on attacking this rose bud – not for long. This rose bud is the only one on this rose bush and is about 3 feet (metre) off the ground

Aphids have a number of natural enemies, and these insects are much better at controlling aphids than any other method available to gardeners. Pampering and nurturing their natural enemies is an excellent method of organic aphid control. Mint, fennel, dill, yarrow, clover, and dandelions are known to attract lacewings, ladybugs, and a type of insect actually called the "aphid predator." Placing these plants around the plants you wish to protect may draw predators capable of controlling the aphid population.
