Oak lace bug
Scientific Name: Corythucha arcuata
Order & Family: Hemiptera: Tingidae
Size: 3 mm - 4 mm in length

Natural Habitat
Deciduous forests and urban landscapes; specifically found on the undersides of oak leaves (Quercus species).
Diet & Feeding
Herbivorous; they pierce leaf tissue with needle-like mouthparts to suck sap from the host plant.
Behavior Patterns
They exhibit hemimetabolous development (egg, nymph, adult). Adults are characterized by their lace-like, transparent wings. They often congregate in large groups on the undersides of leaves, leaving behind dark spots of excrement.
Risks & Benefits
They are a pest to trees, causing 'stippling' or yellowing of leaves and premature leaf drop. They can bite humans occasionally if they land on skin, causing a minor, itchy prick, but they do not transmit diseases.
