ROSE SCALE FACTS |
Identification
Rose Scale is a hard scale. The adult females are white and flat. The males have two forms - sedentary males are long and flat with ribbed texture and are white; winged males are slightly smaller and orange-red with a spine protruding from the rear. Heavy populations of rose scale reduce flowering, stunt growth and in severe cases can cause plant death. Females have two nymph stages, and males have four stages.
Size
Females 2mm - 2.5mm. Males 0.8mm long.
Habitat
found on stems and branches of roses and related plants
Food
feeds on sap from stems of roses, raspberries, loganberries, and blackberries
Breeding
Females lay a batch of around 40 eggs. Pale-red nymphs or crawlers appear in spring
