The western conifer seed bug, Leptoglossus occidentalis, sometimes abbreviated as WCSB, is a species of true bug (Hemiptera) in the family Coreidae. It is native to North America west of the Rocky Mountains (California to British Columbia, east to Idaho and Nevada) but has in recent times expanded its range to eastern North America, and has become an invasive species in parts of Europe.
