The small, dainty Hazelnut Lace Bug comes from a family known to be garden and agricultural pests.
Most Lace Bugs are very partial to one type of plant. For this species, it seems to prefer the Hazelnut tree. They are small and difficult to see as part of their bodies are transparent. Adults eat the bottoms of leaves and suck juices from the host plant, often creating white spots on the tops of the leaves. Their small fecal pellets will also dot the leaves and the stems. An infestation could cause a substantial amount of damage to the plant.
Larvae look very different than adults. They are spiky and dark. They hatch from inside the leaves, where females embed their eggs. This also causes damage.
Scientific Name: Corythucha coryli
Size (Adult; Length): 3mm to 8mm (0.12in to 0.31in)
