It is important to distinguish between silverleaf whiteflies, which cause the most serious damage to peppers, and other whiteflies. You can distinguish between silverleaf whiteflies and greenhouse whiteflies by examining fourth-instar nymphs with a hand lens.
Fourth-instar nymphs of greenhouse whiteflies have long waxy filaments around the edge of their bodies, whereas those of silverleaf whitefly do not. Use the photos below to help you with your identification.

Silverleaf whitefly pupae.
Nymphs are convex or rounded in profile. From above they are oval, whitish, soft and, unlike 4th instar greenhouse whitefly nymphs, do not have filaments.
|
Silverleaf whitefly adult.
Adults hold their wings rooflike over their bodies. The wings do not meet in the back as they do in greenhouse whitefly adults, but have a slight space between them.
|
Greenhouse whitefly with nymphs.
Nymphs are elevated in profile with edges perpendicular like a cake or hat box. They have many long waxy filaments around the edge of their bodies.
|
Greenhouse whitefly adult.
Adults are very similar in appearance to silverleaf whitefly adults, but hold their wings flatter over the back with no space between the wings where they meet in the center.
