About Brown Marmorated Stink Bug
The brown marmorated stink bug (Halyomorpha halys) is a 14–17 mm shield-shaped bug native to East Asia, first detected in Allentown, Pennsylvania in 1996 and now present in most of the contiguous United States and many European countries. It feeds on over 100 plant species including apples, peaches, peppers, corn, and soybeans by piercing tissue and injecting digestive enzymes, causing cat-facing damage to fruit. In autumn it aggregates on buildings and enters through any small gap to overwinter, emitting a distinctive cilantro-like defensive odor when disturbed or crushed.
