Mealybugs

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. In Pachyveria, they often congregate in the crevices between the fleshy leaves and near the base of the rosette.

Very Common

Cottony Scale

Similar to mealybugs, scale insects can produce a white, fuzzy coating. These pests suck the sap from the Pachyveria's succulent leaves, which can lead to yellowing or stunted growth.

Common

Powdery Mildew

Common
