Other: The Brown Marmorated Stink Bug is an exotic species that
was introduced to North America in 2001 from S.E. Asia, where it is
considered to be a significant agricultural pest. Its presence was first
confirmed near Allentown, Pennsylvania. Since that time its range has
expanded with specimens being collected as far west as Oregon.
Identifying characteristics include: overall brown body color, white banding
on the antenna, alternating cream and dark brown stripes on the edges of the
abdomen and a strong odor when crushed or disturbed. As fall
approaches the bug will crawl into protected areas such as buildings to
overwinter. (Hamilton et al, 2003) Note: only a single insect was
found at this location.
