Black Scale (Larvae/Adult)

Commonly found on olive trees, citrus, and various ornamental shrubs in Mediterranean and tropical climates.

Plant sap (phloem). These insects use piercing-sucking mouthparts to feed on the tender twigs and leaves of host plants.

They are largely sedentary as adults, appearing as dark, hard bumps on stems. They excrete a sticky substance called honeydew while feeding, which can lead to the growth of black sooty mold.

Risk: Heavy infestations can cause leaf drop, twig dieback, and reduced fruit production. Benefit: Provide a food source for natural predators like chalcid wasps and ladybugs.
