Scale Insect

Natural Habitat

Typically found on the stems, branches, and leaves of many host plants including houseplants, shrubs, and ornamental trees.

Diet & Feeding

Scale insects are plant parasites that feed on the sap (phloem) of plants using needle-like mouthparts.

Behavior Patterns

Once they reach adulthood, females often become immobile and secrete a waxy, shell-like covering as protection. They remain in one spot for the duration of their life cycle, while males may have wings and are short-lived.

Risks & Benefits

They are considered significant agricultural and horticultural pests. Heavy infestations can weaken plants, cause yellowing leaves, and lead to plant death. They secrete 'honeydew' which can attract ants and promote the growth of sooty mold.
