They have wax glands, the secretions of which make the surface appear like being powdered. The head of the andromeda lace bug is nearly hidden (under a big, black, bullet-shaped bubble on the neck) . Their antennae are an important identifying characteristic. Their simple eyes (Ocelli) are round and small. | | |
| | The andromeda lace bug can multiply in large numbers and appears en masse. The bugs cause mottling on the leaves of plants. Egg-laying is carried out with the aid of an ovipositor. The eggs are very small and transparent and are sunk deep in the leaves’ tissue (usually on the underside). The eggs overwinter there. | | |

The lattice-like structure on the surface of the body (which is characteristic of the species) is not yet apparent on the bodies of the larvae. Like the adult bugs, they are covered with waxy secretions from their glands which make their surface look powdered. The development of the larvae takes place in 5 stages and takes 20 to 70 days depending on climatic conditions Flying larvae are rarely seen. The larva...
...20 to 70 days depending on climatic conditions Flying larvae are rarely seen. The larvae are not very eager to move and often hide in small cavities or between parts of plants, and when disturbed, show little inclination to leave. The andromeda lace bug is primarily regarded as a crop pest by humans. | | |
| The bug is oval in shape and can reach lengths of 3.8 to 5 mm. Their antennae are about the same length as their bodies, and are bright and clearly segmented. The upper side of the body is bare and shiny. Half blankets and neck shield have a dark brown t...
... of the body is bare and shiny. Half blankets and neck shield have a dark brown to black hue and the centre and tips of the wings bear patches of yellowy - red. On the upper side of the insect is a yellow mark in the shape of a small heart. These bugs have large complex eyes. The head and legs are lighter in colour than the rest of the body. There are dark patches on the legs. | | |
| Some species of lace bugs overwinter as adults. After mating, the fertilized females use their ovipositor to lay their eggs almost exclusively on the underside of the leaves of the food plants of their larvae (nymphs). The eggs of some species spend the winter there. The ha...
...not have wings, these are formed only from the 2nd and 3rd stage on, and are fully developed by the end of the last larval stage. In most species larval development occurs in 5 stages, in some species, just 4. The metamorphosis of the larvae of lace bugs is incomplete because it does not involve a pupal stage. The transition from nymph to adult lace bug is finished with the last moult. The nymphs of some species of lace bugs overwinter on the food plants. | | |
