Mealybug (likely a cottony mealybug)

Plant surfaces, especially leaf axils, stems, roots, and sheltered undersides of leaves; commonly found on houseplants, ornamentals, and crops.

Pierces plant tissue and sucks phloem sap. It may cause yellowing, wilting, stunted growth, and sticky honeydew deposits.

Slow-moving, soft-bodied insects covered in white wax; females often cluster in protected areas and produce cottony egg sacs. Honeydew can attract ants and promote sooty mold.

Not dangerous to people, but infestations can weaken or kill plants and may spread between plants. They provide limited food for predators such as lady beetles and lacewings.
