Boxelder Bug

The Boxelder bug, Zug, or Maple Bug (Boisea trivittat) is a supremely annoying insect which can be found on or near  Box Elder (Acer negundo), other Maples, Ash, and Goldenrain Tree (Koelreuteria paniculata). Adults about a half inch long and mostly dark brown or black, with red veins or markings. Nymphs are mostly red.These bugs are similar in appearance to stink bugs and can put off an order if they feel threatened.

They are not known to be particular distructive and are not considered an agricultural threat. But let me tell you from personal experience that these bugs congregate in the hundreds on hardscape, door frames, etc. near their host trees and can be quite a nuisance. I have only just noticed these pests in large number recently, but they can be active outdoors from spring through fall. They also hibernate in walls and behind siding through the winter.

*Update: 30 minutes after I posted, I noticed a Zug walking across my desk! My office walls have been breached.
