Bugs are frequently puzzled with lacewings, which may be an error that is dangerous. Lacewings are helpful bugs that prey on aphids, bugs and other herbivorous insects. Bugs, nevertheless, are feeders capable of causing considerable damage. Rhododendron- lace bugs that are feeding belongs to the family Tingidae in the in the region of of true bugs. Easily identified by by its own lace-like ridges and wings along the pronotum–the area supporting the the top–these bugs are about 1/8 inch-long and grayish in colour.
Females lay eggs, concealed by their shiny droppings, on the lower of rhododendron leaves. The tiny, wingless nymphs feed and hatch through five or four molts. Both nymphs and adults are generally present on a plant depending on the species. The bugs overwinter as grownups or as eggs, hiding in leaf litter and under bark.
Rhododendron lace bugs prey on the lower of the leaves. They suck the liquid from plant cells using their mouths that are piercing.

Spraying bugs immediately using a contact insecticide like insecticidal soap or neem oil will eliminate the pests with minimal threat to advantageous bugs.
