Boisea rubrolineata - Western box elder bug
Identification: Adults are about 1/2 inch long (1.25cm). Oval-shaped black body with red or orange lines on their body and forewing. Immature stages have bright red bodies and are wingless. Are often found crawling or aggregating on the ground and range from a few mm to 1 cm in length.
Notes: Native to western North America.
Pest Status: Nuisance pest. Adults and nymphs feed on seeds of maple trees, but do not cause damage to tree. Populations get very large in spring and summer, but infestations are relatively short.
Management: Pesticide applications are not recommended, as populations are widespread. Exclusion via sealing of entry points (windows, doors) is recommended.
