Whiteflies are tiny flying insects that can be a nuisance in gardens and indoor plants. They have a slender, elongated body and four transparent wings that are usually yellow or white in color.
Adult whiteflies are about 1/16 inch long and have a distinctive wingspan. They are often mistaken for small aphids or thrips.
There are several common types of whiteflies, including the greenhouse whitefly, the sweet potato whitefly, and the silverleaf whitefly.
The greenhouse whitefly is one of the most common types of whiteflies and can be found in a wide range of plants, from vegetables to flowers.
What Are Whiteflies?
Whiteflies are a type of insect that can be a nuisance to gardeners and plant enthusiasts. Adult whiteflies can be identified by their white, waxy coating and parallel wings.
They come in two major types: the greenhouse whitefly and the silver leaf whitefly. Adult greenhouse whiteflies are slightly less than 1/8 inch long, while silver leaf whiteflies are a bit smaller.
Female whiteflies are multi-taskers, eating and laying eggs at the same time. They feed on the underside of leaves by inserting their short, needlelike beak into the foliage and sucking out the plant juices.
What's a Whitefly?
Whiteflies are tiny insects that can cause big problems for plants. They're usually less than 1/8 inch long and have a white, waxy coating.
There are two main types of whiteflies: the greenhouse whitefly and the silver leaf whitefly. Adult greenhouse whiteflies are slightly larger than the silver leaf whitefly.
Whitefly adults are a bit sneaky - they can eat and lay eggs at the same time. This means they're constantly feeding on plant juices while also producing eggs.
Whiteflies feed on the underside of leaves, sucking out the plant juices with their short, needlelike beak. This can cause wilting, yellowing, stunting, leaf drop, or even death in severe cases.
Female whiteflies don't even stop eating to lay eggs - they just turn their beak around and lay eggs in a semicircle around the feeding site.

Are Whiteflies?
Whiteflies belong to a group of over 1,500 species of soft-bodied, fly-like insects. They get their name from the powdery white wax that coats adult whiteflies.
These insects are notorious for spreading plant diseases and damaging a wide range of crops. They can multiply rapidly, making infestations difficult to control.
Whiteflies are infamous for the burden they place on growers worldwide. Their ability to quickly reproduce makes them a persistent problem for farmers.
Identifying Whiteflies
Identifying whiteflies can be a challenge, but there are some key things to look out for. Adult bandedwinged whiteflies have distinctive brown stripes on their wings.
To get a better sense of what you're looking for, it's worth noting that different species of whiteflies have subtle physical differences. For example, greenhouse whiteflies hold their wings together without spaces between them, while silverleaf and sweet potato whiteflies have gaps between their wings.
Here are some common symptoms of whitefly damage to look out for:
- Chlorotic spots
- Leaf yellowing
- Shedding leaves
- Stem blanching
- Dying plants, in severe cases
Keep an eye out for these signs and you'll be well on your way to identifying whiteflies in your garden.
Whitefly Description:
Whiteflies are insects that can be tricky to identify, but understanding their physical characteristics can help. They have four white wings, two segmented antennae, and a yellow body.
Their bodies are also coated with a white, waxy powder. This waxy coating is a distinctive feature of whiteflies.

Whiteflies can be found in various stages of their life cycle, and each stage has a distinct appearance. The eggs are laid on the underside of plant leaves and are initially white or light tan, but darken to blue or purple before hatching.
Newborn whiteflies resemble tiny scale insects with flat, oval, greenish-yellow bodies. As they grow, they darken to cream or yellow.
Some whitefly species have physical differences that can help with identification. For example, adult bandedwinged whiteflies have brown stripes on their wings, while greenhouse and sweet potato whiteflies don’t have markings.
Here are some common whitefly species and their distinguishing features:
Keep in mind that the physical differences between whitefly species can be subtle, so it's often easier to identify them by the symptoms they cause on plants.
Five Common Types
Whiteflies are a common pest in greenhouses and outdoor gardens, and knowing the different types can help with identification and management. The Greenhouse Whitefly, for example, has white wings and a yellow body surface.
One of the key characteristics of the Greenhouse Whitefly is that it cannot survive in colder temperatures outside of greenhouses. This makes it a unique pest that thrives in controlled environments.
The Silverleaf/Sweet Potato Whitefly has a distinctive yellow body and white wings that are vertically tilted, creating a 'tent' shape. This shape is a dead giveaway for identification.
The Giant Whitefly can grow up to 3/16 of an inch long, making it one of the larger whitefly species. This size difference can be an important factor in distinguishing it from other types.
The Citrus Whitefly has a white body and wings, and it favors warmer climates. This makes it a common pest in regions with mild winters and hot summers.
