where did all the stink bugs come from
Brown marmorated stink bug Halyomorpha halys, also known as the brown marmorated stink bug (BMSB), is an insect in the family Pentatomidae that is native to China, Japan, the Koreas, and Taiwan.[2] It was accidentally introduced into the United States, with the first specimen being collected in September 1998.[3] The brown marmorated stink bug is an agricultural pest[4] and by 2010â€“11 had become a season-long pest in U.S. orchards.[5] It has recently established itself in Europe and South America.[6]
Skunk Skunks are notorious for their anal scent glands, which they can use as a defensive weapon. They are similar to, though much more developed than, the glands found in species of the family Mustelidae. Skunks have two glands, one on each side of the anus. These glands produce the skunk's spray, which is a mixture of sulfur-containing chemicals such as thiols (traditionally called mercaptans), which have an offensive odor. A skunk's spray is powerful enough to ward off bears and other potential attackers.[citation needed] Muscles located next to the scent glands allow them to spray with a high degree of accuracy, as far as 3 m (10 ft). The smell aside, the spray can cause irritation and even temporary blindness, and is sufficiently powerful to be detected by a human nose up to 5.6 km (3.5 miles) down wind.[citation needed] Their chemical defense is effective, as illustrated by this extract from Charles Darwin's Voyage of the Beagle:
