Aphid exuviae (Cast skins)

Natural Habitat

Found on the undersides of leaves, stems of plants, or nearby surfaces where aphids aggregate.

Diet & Feeding

The living insects suck plant sap (phloem); the objects shown are non-feeding discarded exoskeletons.

Behavior Patterns

As aphids grow, they molt their rigid exoskeleton several times. These white, flaky shells are often left behind in clusters, frequently mistaken for live insects or whiteflies.

Risks & Benefits

The presence of these skins indicates an active or recent aphid infestation, which can cause plant yellowing, leaf curling, and the spread of plant viruses.
