Aphids are tiny insects that feed on the sap of a wide range of plants. There are thousands of species, but colors range from green to yellow and red to black. The most common aphid color is green because they blend in with the leaves they live on. Aphids damage plants by sucking out their juices and excreting a sticky substance called honeydew. Honeydew can be a home for other pests like ants, wasps and bees. Aphids can also infect your plants with viruses that weaken or kill them eventually if left untreated.
In May, many aphids are feeding on the new growth of asparagus, aphid-tolerant crops like lettuce, and other annual herbaceous plants.
In May, many aphids are feeding on the new growth of asparagus, aphid-tolerant crops like lettuce, and other annual herbaceous plants. As these crops grow larger and more vigorous in the heat of summer, they will provide an important food source for aphids.
When are Aphids Most Active?
Aphids can be found throughout the year wherever there is a suitable plant host; however, in May many species start to build up populations and become active at around this time of year (depending upon weather conditions). The majority of species are active during warmer months when temperatures reach above 80 degrees Fahrenheit (27 degrees Celsius). During winter months some species will hibernate underground in crevices or under dead leaves until spring arrives again.
Some species of aphid will overwinter (remain active through the winter) in a protected part of a garden such as under bark or in the shelter of a stone wall.
Some species of aphid will overwinter (remain active through the winter) in a protected part of a garden such as under bark or in the shelter of a stone wall. Others may hibernate on the branches of trees or shrubs. These insects are inactive during cold weather and will come out when temperatures rise and food is available again.
The warm weather of spring starts them moving again and when temperatures reach about 60 degrees Fahrenheit, they begin to feed.
You may be wondering, “Where do aphids come from?” Aphids can be found in many places, but they seem to have a preference for plants that have thick leaves and stems. These plants include rose bushes and hydrangeas.
When Are Aphids Most Active?
The warm weather of spring starts them moving again and when temperatures reach about 60 degrees Fahrenheit, they begin to feed. They are most active when the temperature is in the 60’s or higher but can be active at temperatures of 50 degrees or higher as well.
Aphids feed by inserting their mouth parts into plant tissue and sucking up the plant’s sap, which is rich in sugar. They excrete excess sugar from holes in their posterior ends called cornicles.

The feeding process causes leaves to curl or turn yellow and eventually wither and fall off in some cases, resulting in wilted plants with a sparse appearance. In addition to the unattractive appearance of infested plants, aphids spread disease as they move from plant to plant while feeding. Some species can kill crops such as soybeans if left uncontrolled (1).
These tiny pests can easily be controlled by natural predators like ladybugs, lacewings and parasitic wasps; however chemical control may be necessary when these natural predators aren’t available or an infestation becomes too severe for them alone to handle effectively enough
Aphids are active all year round but peak activity occurs from late spring to early summer when temperatures start to rise and food supply increases by way of new growth on plants.
Aphids are active all year round, but their peak activity occurs from late spring to early summer when temperatures start to rise and food supply increases by way of new growth on plants.
As aphid populations grow, they tend to migrate into surrounding areas where there is more suitable plant material available for feeding. This often results in a large population explosion of aphids – known as an infestation – damaging crops or other plants growing nearby.
Aphid populations can explode in mid-summer on plants that thrive in hot weather like beans and tomatoes.
Aphids are a problem on many kinds of plants, but are especially problematic on plants that thrive in hot weather. Aphids can be found from early spring through the fall, but they’re most active in midsummer. They feed on a wide range of plants and have been known to damage crops such as beans, tomatoes and roses.
During the summer months, aphids feed on many kinds of plants.
Aphids are most active during the summer months, when you’ll find them feeding on many kinds of plants. They feed on the new growth of plants and prefer to feed on the leaves and stems. Aphids are also found on lettuce, asparagus and other annual herbaceous plants.
You should be able to tell when aphids are most active by learning about the different types of aphids and their feeding habits. While some species like to feed on plants with soft stems or leaves, others prefer hardy perennials that can withstand their feeding. It’s important not just for gardeners but also farmers in rural areas who rely on crops such as wheat and corn for their livelihoods.
