Aphid On Stem

....Size: X 10
Aphids live in colonies where males are usually rare or absent, & the females often produce live young.
When conditions become crowded, the aphids become restless, their body size & fertility decreases & more winged forms are produced so that they can migrate to start new colonies.
Some species of aphids are notorious vectors of viruses.
Aphids prefer cooler weather, in the sub tropics they are most common in the Spring & Autumn.
Their natural enemies are usually very effective & they include Ladybirds & their larvae & the larvae of Lace Wings.
Ants may exacerbate aphid problems.
Ants remove from the site of the aphids their excretion commonly called honey dew.
The colour of aphids range from green, brown, red & near black.
