Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions that Sedum multiceps prefers during summer. They pierce the succulent leaves to feed on cell contents, leaving behind fine silk webbing as they build colonies.

Tetranychus urticae (European Red Spider Mite)

This specific species is highly common in succulents like Sedum; the webbing often becomes more dense around new growth or tight leaf clusters where humidity is slightly higher.

Very Common

Extreme Low Humidity/Desiccation

While not a direct cause of webbing, extremely dry air can cause the plant to produce more fine, hair-like structures or make existing structural fibers more visible. However, this is usually accompanied by shriveled leaves rather than actual silk.

Common

How to confirm: Check if the soil has dried out completely for an extended period and if the leaf texture feels soft rather than firm.

3 Monitor the soil moisture levels to ensure the plant is not being overwatered while the air is dry, as root rot can also cause structural stress.
