Short answer
Your Parlor Palm is suffering from a spider mite infestation, which thrives in the dry indoor air often found in homes. The most effective fix is to physically wash the fronds thoroughly with lukewarm water to remove the mites, followed by regular applications of neem oil and increased humidity.
Spider mites are a common pest for Chamaedorea elegans, appearing as fine webbing between leaflets and causing yellow or white speckled stippling on the foliage. While these mites can be persistent, they are usually manageable if you catch the infestation early before the plant suffers significant tissue damage.
These tiny arachnids congregate on the undersides of Parlor Palm leaves, sucking sap and leaving behind speckled damage known as stippling. They are particularly drawn to this species because the delicate, feathery fronds provide ample hiding spots and the indoor environments where these palms are kept often lack sufficient humidity.
Check: Look closely at the underside of the leaves with a magnifying glass to see tiny moving dots or tap the frond over a white sheet of paper to see if dark specks fall off.
Fix: Isolate the plant, rinse all surfaces of the leaves under a lukewarm shower, and apply neem oil every 5-7 days for at least three weeks to disrupt their lifecycle.
Parlor Palms prefer moderate humidity and can become stressed when kept in dry, heated indoor air. While low humidity alone won't create webs, it creates the ideal environment for spider mites to reproduce rapidly and weakens the palm's natural defenses.
Check: Check the brown, crispy tips of your leaflets; if they are brittle and the air feels dry to the touch, humidity is likely below 40%.
Fix: Group your palm with other plants or place it on a pebble tray filled with water to increase localized moisture levels.
Sometimes, owners mistake the natural shedding of the oldest, lowest fronds for a pest issue. However, natural aging results in gradual yellowing and browning without the fine webbing or pinpoint stippling characteristic of mite damage.
Check: Examine the webbing; if there is no webbing or stippling on the younger, upper fronds, the damage is likely just the natural senescence of older growth.
Fix: Simply prune away the fully yellowed or brown fronds at the base to keep the plant looking tidy.
When to worry
You should take urgent action the moment you spot webbing, as Parlor Palms have a high density of leaves that allow mites to spread quickly and cause irreversible foliage loss.

Diagnose my Parlor PalmWhile you can use commercial insecticidal soaps, avoid heavy-duty synthetic pesticides, as Parlor Palms can be sensitive to harsh chemicals that might burn their delicate foliage.
Only remove leaves that are heavily infested or dying; removing too much of the canopy at once can stress the plant further and inhibit its ability to photosynthesize.
Unfortunately, the speckled damage is permanent and those specific leaflets will not turn green again. You are treating the plant to prevent further damage to new, healthy growth.
