Corythucha
lace bugs
Corythucha is a large genus of lace bugs (family Tingidae) comprising approximately 75 described species, primarily distributed in the northern hemisphere including North America, Europe, and eastern Asia. Members of this genus are small, sap-sucking true bugs characterized by their distinctive reticulated, lace-like forewings and pronotal expansions. Several species are economically significant pests of ornamental and crop plants, including the sycamore lace bug (C. ciliata), oak lace bug (C. arcuata), cotton or bean lace bug (C. gossypii), and chrysanthemum lace bug (C. marmorata). Some species exhibit notable behavioral traits such as maternal care (C. hewitti). The genus has been subject to extensive invasion biology research due to the rapid spread of several species through human-mediated transport and natural dispersal.
Neochlamisus platani
sycamore leaf beetle
Neochlamisus platani, commonly known as the sycamore leaf beetle, is a small leaf beetle in the family Chrysomelidae. Adults are bronze to brown in color with a rough, bumpy exoskeleton that provides camouflage against bark and debris. The species is tightly associated with its host plant, the American sycamore (Platanus occidentalis), where it feeds, mates, and oviposits. Both adults and larvae consume sycamore foliage, and heavy infestations can reduce foliage mass and damage ornamental value.
