The most common aphids on houseplants are the light green ones (pear aphids), but aphids can also be found colored pink, white, grey and black. Additionally, winged aphids can appear when colonies are established and fly to infect new plants. Juvenile aphids (nymphs) look like smaller versions of the adults. Aphid infestations tend to develop quickly, and the insects are highly mobile: they rapidly travel from one plant to another. In the outdoor garden, aphid colonies are often tended by ants, which feed on aphid honeydew — a sugary liquid that is secreted by aphids as they feed on sap.
Indoors, aphids spread between plants by flying or crawling. Aphids cause damage by sucking sap from new growth on plants. They tend to cluster at the growth end of plants and attach themselves to the soft, green stems. As a result, the new foliage may look crinkled or stunted, with the aphids usually plainly visible around the stem. If the infestation is bad enough, the plant will begin to drop leaves. Finally, like mealy bugs, the honeydew secreted by aphids can encourage the growth of sooty mold and fungus.
Outside, aphid eggs survive the winter by attaching to woody growth. The females give birth to nymphs without mating, and these nymphs rapidly mature into adults (in about 10 days). Males are born in the fall and begin to mate with the females to produce eggs in preparation for the long winter. Indoors, however, there is no winter to slow their reproduction, and female aphids can continue to produce nymphs all year without pause. Thus, the aphid population can quickly get out of control on indoor plants. Like most pests, the best control for aphids is defensive. Healthy, vigorous plants are less susceptible to infestation than weak, under potted, and stressed plants. As a general rule, if you make sure your plants are healthy, you're less likely to attract these annoying critters in the first place. If you see aphids on your indoor plants, there are many control options, most of them non-chemical. How To Spot, Treat, And Prevent Aphids On Cannabis Plants.

The term aphid is used to refer to a group of small sap-sucking insects that count as one of the most destructive pests on cultivated plants. Aphids can vary in size from roughly 1 to 10 millimetres and can be green, black, red or white in colour. The most common kind of aphids found in home gardens are usually green and about 1 millimetre long. They have two whip-like antennae at the tip of the head and oppositely a pair of tube-like structures, called cornicles. Winged female aphids usually hatch at the beginning of spring and give birth to more female nymphs.
Within a few weeks, these nymphs give birth to more young. This process is repeated several times, allowing aphid numbers to rise dramatically in a short amount of time.
By the end of the summer, aphids develop sexual forms (males and females) and mate to produce overwintering eggs. Most aphids, except for the sexual forms, do not need to mate in order to reproduce and are able to produce live young. There are over 4,000 aphid species found around the world.
