Short answer
Your Echeveria elegans is likely suffering from a spider mite infestation, which thrives in the dry indoor conditions this succulent prefers. The most effective fix is to physically wash the leaves and apply insecticidal soap or neem oil repeatedly over three weeks to break their life cycle.
Seeing fine webbing and tiny speckled, stippled marks on your Echeveria elegans is a clear warning sign of pest activity rather than a cultural care error. While these succulents are otherwise hardy, their preference for low-humidity environments makes them highly susceptible to spider mites, which can quickly drain the plant's vitality if left unchecked.
Spider mites are tiny arachnids that feed on the sap of your Echeveria, causing the characteristic stippling or bleaching effect on the leaves. The fine webbing is their signature move, often found nestled between the tight rosettes of the succulent.
Check: Look closely at the underside of the leaves or the crevices of the rosette with a magnifying glass to spot tiny, moving translucent or reddish dots.
Fix: Isolate the plant, rinse the foliage thoroughly under a gentle stream of lukewarm water, and apply insecticidal soap or neem oil every 5-7 days for at least three weeks.
Because Echeveria elegans thrives in bright, direct light and dry soil, any sudden shift in temperature or airflow can weaken its defenses. A stressed plant is significantly more attractive to opportunistic pests like spider mites.
Check: Check if your plant has recently been moved to a new location or if the local room temperature has fluctuated significantly.
Fix: Ensure the plant is receiving at least 6 hours of bright, direct light and maintain stable temperatures, moving the plant away from drafty windows or heating vents.
While mealybugs usually present as white, cottony tufts, their damage and the fine, sticky honeydew they secrete can sometimes be mistaken for web-like structures. They also target the tender growth points of your succulent.
Check: Check for small, white, fuzzy masses in the leaf axils or base of the rosette that feel sticky or powdery to the touch.
Fix: Dip a cotton swab in 70% isopropyl alcohol and dab it directly onto the insects to kill them, followed by a systemic insecticide treatment if the infestation persists.
When to worry
If you notice the rosettes losing their firm shape, turning yellow, or dropping leaves rapidly, the infestation has reached a critical stage that threatens the plant's structural integrity.

Diagnose my EcheveriaIncreasing humidity is a great preventative measure, but it will not kill an existing, active infestation on your Echeveria. You must physically remove the mites and apply a treatment alongside the humidity change.
Repotting is usually unnecessary and can stress the plant further; it is better to treat the foliage directly. Only repot if you suspect the soil is also infested or if the plant has been overwatered.
Unfortunately, the speckled damage is permanent scarring caused by the mites feeding on the plant cells. New, healthy growth will emerge from the center, and you can eventually prune away the damaged outer leaves once the plant is healthy.
