Boxelder Bugs - Leptocoris trivittata  Whitney Cranshaw, Colorado State
University, www.forestryimages.org
 HOSTS: Boxelder, ash, and maple. DESCRIPTION:
Boxelder
bugs are brownish-black and about 1/2 inch long. They have three red
lines on the head and a bright red abdomen beneath the wings. LIFE
CYCLE: Adults
overwinter in protected sites (including homes). They emerge in
mid-spring and lay eggs. The first generation nymphs feed on the
boxelder, ash, and silver maple seeds, fruit trees and various low
growing plants until they become adults in mid-summer. Females then lay
eggs on the seeds of boxelder trees. The nymphs mature on these seeds
into late fall. After the first frosts boxelder bugs move to winter
shelter; during this time they invade buildings. CONTROLS:
No control
required. Nusiance pest only – will not harm plants or
buildings. Vacuum up the bugs and seal the cracks in foundations and
windows to keep the bugs from entering the buildings. |
