Halyomorpha halys - Brown marmorated stink bug
Size: 13 – 19 mm
Description:
Greyish brown and marbled upper body, sometimes slightly purplish on the hemeleytra. Legs are light tan to white with dark spots on the femora. Alternating light and dark banding along the edge of the abdomen is usually visible from above. Pronotum without serrations along the edge, unlike Brochymena or Euschistus. Antennae are dark with distinct light bands. Nymphs usually have black and red abdomens with black thorax and heads, and are very active when disturbed.
Hosts:
Very wide host range. In Oregon, commonly found in urban areas on English holly, catalpa, 5th instar paulownia, himalayan blackberry, and hazelnut. In the Mid-Atlantic states, H. halys is a significant economic crop pest as well as an urban nuisance pest. H. halys is expected to be a significant economic pest in Oregon and is already a nuisance pest in many areas due to its habit of aggregating on the sides of buildings and inside homes.
Range: In Oregon, northern region of the state from Hood River to Portland, along the Willamette Valley south to Medford. Also found in coastal counties. In the United States, found in 38 states and established as pests in Oregon, Washington, and the Mid-Atlantic region.
Management: Currently, management methods for H. halys are limited. For pesticide information, please visit stopbmsb.org's page.
