Corythucha pergandei
Alder Lace Bug
Corythucha pergandei, commonly known as the alder lace bug, is a species of true bug in the family Tingidae. It is native to and distributed throughout North America, with records from both Canada and the United States. Like other lace bugs, it is a sap-feeding insect that typically inhabits the undersides of leaves. The species is associated with alder (Alnus) as its primary host plant, from which it derives its common name. As with other members of the genus Corythucha, it likely causes characteristic white stippling damage on foliage through its piercing-sucking mouthparts.
