The pupal case is opaque after emergence of the adult and the case may collapse and lose its shape.
Eggs are brown and have a hexagonal patterned surface.
Dialeurodes citrifolii pupae are readily confused with D. citri , but citrifolii is said to be somewhat larger. I prefer a microslide to be certain of the identification. The eggs can readily be separated because D. citrifolii eggs are dark brown and have a hexagonal pattern on the surface, while D. citri eggs are lighter in color and nearly smooth.
