Where would you expect to find citrus white fly on a plant?

Citrus white flies are typically found on the underside of leaves. This is primarily because the underside provides an ideal microenvironment that offers shade and protection from natural predators as well as harsh weather conditions. The whiteflies settle and feed on the sap of the leaves, which can cause stress to the plant and potentially lead to disease transmission. They excrete honeydew, which can create conditions conducive to sooty mold growth.

In contrast, tender twigs, wood portions of plants, blossoms, and fruit are not the typical habitats for these insects. While white flies may occasionally be found near these areas, their primary activity, including feeding and reproduction, occurs on the leaves, particularly on the undersides where they can more easily evade detection and threats.
