Mealybugs

These small insects secrete a waxy, white substance that looks like cotton to protect themselves. In Conophytum species, they often hide in the crevices between the leaf pairs or near the base of the plant.

Very Common

How to confirm: Use a toothpick to gently probe the white spots; if the 'cotton' moves or reveals tiny insects underneath, it is mealybug infestation.

Fungal Mold (Botrytis or Sclerotinia)

High humidity or poor air circulation around the succulent leaves can cause fungal mycelium to appear as white, fuzzy patches. This is particularly common in Conophytum during their dormant period if moisture remains trapped.

Common

Powdery Mildew

This fungal disease manifests as a white, dusty coating on the surface of the leaves. While more common in leafy plants, extreme humidity can cause it to appear on certain succulent species.

Common

How to confirm: Rub the white spot with your finger; powdery mildew will often wipe off easily like dust, unlike mealybugs which are physically attached to the plant.
