Scale Insect Identification in South Florida
Scale insects are destructive plant pests commonly found throughout South Florida, especially on ornamental plants, shrubs, palm trees, hedges, fruit trees, and tropical landscapes. These pests feed on plant sap and are known for weakening plants, yellowing foliage, causing branch decline, and producing sticky honeydew residue that promotes mold growth. Scale insects are small immobile pests that attach themselves to stems, leaves, and branches beneath protective waxy or shell-like coverings. The scientific classification for scale insects falls within the superfamily Coccoidea, and they are also commonly referred to as soft scales or armored scales depending on the species.
What Are Scale Insects?
Scale insects are sap-feeding pests that damage plants by attaching themselves to foliage and extracting plant fluids.
Unlike mobile chewing insects, scale insects often remain fixed in place beneath protective coverings while feeding.
Heavy infestations may weaken ornamental plants and contribute to branch dieback.
How to Identify Scale Insects
Common identifying characteristics include:
- Small shell-like bumps on plants
- Brown, white, or tan protective coverings
- Sticky honeydew residue
- Yellowing leaves

- Black sooty mold growth
Scale insects commonly blend into stems and branches.
