Corythucha cydoniae
hawthorn lace bug
Corythucha cydoniae, commonly known as the hawthorn lace bug, is a native North American lace bug species in the family Tingidae. It is a documented pest of woody rosaceous plants, with principal hosts including hawthorn (Crataegus), serviceberry (Amelanchier), firethorn (Pyracantha coccinea), and cotoneaster. The species has been recorded across much of the United States, Canada, and Central America. Research indicates temperature-dependent development with thermal thresholds around 13-15°C, and reproductive diapause induced by photoperiods shorter than 13:11 (L:D) at 24°C.
