Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often preferred by Begonia Monza Appleblossom. They pierce cell walls to feed on sap, leaving behind fine silk webbing and causing the leaves to develop pale, stippled spots.

Broad Mites

Unlike spider mites, broad mites are microscopic and don't produce visible webs, but they can cause leaf distortion and secondary silk production from other pests. They primarily attack the tender new growth of Begonias.

High Humidity/Mold Growth

While not true webbing, certain fungal hyphae can appear as fine, hair-like structures on Begonia leaves in extremely high humidity environments. This is often accompanied by soft rot if the air circulation is poor.

Common

How to confirm: Check if the 'webbing' feels fuzzy or organic rather than silken and look for any dark, mushy spots on the leaf edges.
