A typical life cycle begins with adult female aphids that give birth to female nymphs, who may also be already pregnant without the involvement of male aphids this leads to very quick reproduction.
Aphids have nearly 400 species all in different shapes, sizes, and colors. It is a member of the superfamily Aphidoidea, also commonly called greenfly and blackfly, these names are given because of its body color including green, black, white, red, orange, yellow.
This plant pest sucks plant juice causing it to lose plant nutrients which stunt its growth and eventually die.
You can identify whether your plant is affected by aphids – looking misshape, curling, yellow, or stunt leaves. These are common signs of aphids present, also check the underside of the leaves.
Aphids love to hide there to protect themselves from sunlight and pest predators. If your plant stem or leaves are covered with sticky fluid, that also points to aphids. The sticky substance is honeydew, it is sweet and attracts other insects like ants to eat on plants.

Spider mites are tiny 8 legged insects. It is a micro-organism that is invisible from naked eyes. This insect belongs to the Acari family TetrantychidaeI, which has around 1200 species. Many species of spider mites are so common in North America that they often attack indoor and outdoor plants, especially greenhouse plants.
Spider mites damage by sucking the plant’s juice that causes tiny spots or stipplings on the leaves. They infest in hundreds on the plant but, then also remain invisible from naked eyes.
You can identify spider mites’ presence by webbing on the leaves and branches of the plants.
Spider mites reproduce quickly by hatching eggs in hundreds in a day. So it’s vital to get rid of spider mites quickly. There are many natural and chemical methods for spider mites treatment.
A bagworm is a moth that feeds on shrubs and trees in its larvae stage. This is a peaky plant pest with a small-diamond-shaped body, which mostly appears in the rainy season. It likes to feed on green plants, vegetables, fruits, perennial plants, flowers.
Bagworms are caterpillars or larvae stage pests that stunt a plant’s growth by constantly feeding its leaves. They start making cocoons on the host plant. A cocoon is a bag-like structure in which bagworms hibernate to evolve. Initially, these cocoons are 1 ⁄ 8 inches long and grow bigger during summer from which caterpillars thrive.
Bagworms are not poisonous but they feast on the plant’s foliage that causes its death.
Talking about the life cycle:
- The bagworm’s life cycle begins from June first week with eggs hatch. They complete their growth by August or early September.
- The bags are 1-2 inches long and strongly attached to the plant’s stems.
- In the late summer when the bags grow bigger, the puppet inside transforms into moths.
- There are two types of moths that hatch from bag wing and wingless. Moths with wings are male moths that come out from the bag and fly to that bag that contains female moths.
- Male moths mate with female moths and mate inside the bag. The female moth then that hatch 200 to 1000 eggs in the bags and die inside.
- The eggs remain inside until spring (June first week) then start hatching. It’s better you keep a shape eye on your plant and get rid for bagworms in its early stage of the life cycle. You can learn about how to get rid of bagworms from this post.
Cabbage worms are common plant pests that are mostly found in kale, cabbage, cauliflower, broccoli, and other members of the Cabbage family.
Do not worry after seeing a few holes in the foliage, vegetables can withstand much leaf loss without any consequences. The true damage from cabbage worms occurs in the early stage (seedling level). It eats all growing leaves and destroys plants’ growth.
Cabbage worms are light green and hide the underside of leaves which makes it extremely difficult to identify them on green leaves. The worm later transforms into white butterflies with tiny black making.
The insect might look appealing in the garden but sooner, it starts laying hundreds of eggs underside of the leaves. These eggs are invisible from naked eyes, so you might not see them until it’s too late. This leads to hundreds of tiny worms that will eat up your plant.

There are two types of cicadas- one that appears annually and the other that comes in every 13 to 17 years like Magicicada septendecula, Magicicada Cassini, Magicicada septendecium. When cicada varieties that appear in 13 to 17 years are called had cicada plagues in which many crops get destroyed.
Getting rid of cicadas varieties is extremely difficult and requires heavy pesticides, cover your skin and wear a hat when dealing with the onslaught.
Cicadas come from the ground during the warm climate or summer. To protect your plant from cicadas often spray strong hose or wasp small trees with landscape netting.
The young cicadas will not feed on leaves but go to roots and suck put the sap of the trees. Adult female cicadas will cut into the bark of the trees and lay eggs. A big tree can survive, not young once may not.

A single female earworm can lay about 500 to 3000 eggs. These eggs are not visible from naked eyes (each egg is smaller than a pinhead).
Eggs hatch within two to ten days, from which larvae of this moth appear. After hatching they immediately start to feed on plants.

Cucumber beetles leave their hibernation site in mid-April to early June. Then right way feed on plants as they are emerging, usually kill themself.
Their larvae feed on host roots and veins, gradually grow in adults during mid-July to early September. As they grow adult they keep feeding on plant’s leaves, fruits, vines, and leaves a deep mark of ruin on the host.

The best way to identify them is by looking at the damage they cause. Flea beetles feed on young plant leaves and make small holes into them.
They feed on seedlings’ leaves making small holes and lay eggs on the roots. When these eggs hatch, their larvae feed on roots. It is important to prevent them from infesting young plants.
Big and mature plants are mostly not affected by flea beetles’ leaf feeding, as they make very small holes. However, the main problem is caused by bacterial diseases they cause like wilt and blight from plant to plant. So it’s essential to get rid of Flea beetles quickly.
In 1912 the USA made it illegal to import rooted plants. Unfortunately, due to lack of implementation of the law, Japanese beetles entered the USA and spread on a large scale before being controlled. Since then every year thousands of plants get infested by them.
Identifying Japanese beetles is easy because of their bright blue-green color. Also, they feed on the plant’s leaves and make it look like a net.
These beetles feed every plant they find, in the garden they have some specific plants like roses, beans, raspberries, and grapes.
