Mealybugs

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cotton-like substance to protect themselves. They feed on the sap of Pachyveria, often congregating in the crevices between the succulent leaves.

Very Common

Powdery Mildew

This fungal disease presents as a white, flour-like coating on the leaf surfaces. In Pachyveria, it often occurs when there is high humidity combined with poor air circulation around the tight rosette.

Common

How to confirm: Rub the white spot with your finger; if it wipes off easily like dust rather than being embedded in the tissue, it may be fungal.
