Two-Spotted Spider Mite Infestation

The fine webbing is a hallmark sign of spider mites, which thrive in the warm, dry conditions often experienced by Sedum makinoi. These microscopic arachnids pierce the succulent leaves to suck out chlorophyll, leading to stippling and eventual leaf drop.

Tetranychus urticae (European Red Spider Mite)

A specific subset of spider mites that is highly prevalent in indoor succulent collections. They create dense silk webs to protect their eggs and move between the fleshy leaves of the Gold Stonecrop, causing a dusty or dull appearance.

Very Common

High Humidity/Microclimate Mold

While less common, extremely high localized humidity without airflow can cause fine fungal hyphae to appear web-like across the leaf surface. This is usually accompanied by a musty smell and softened leaf tissue.

Common

How to confirm: Check if the webbing feels sticky or organic rather than dry and structural like silk.

1 Improve air circulation around the plant by using a small fan or moving it to a less stagnant area to reduce localized humidity.

2 Gently wipe the leaves with a clean, dry cloth to remove the fungal hyphae and prevent further spread.

3 Monitor soil moisture levels closely to ensure the substrate is not staying too wet, which can contribute to high microclimate humidity.
