Yan Bingwu (Chinese, B. 1954) & Yang Wenqing (Chinese, B. 1951) "Assassin Bug" Signed lower right. Watercolor on Silk/Rice Paper. Provenance: Collection of James A. Helzer (1946-2008), Founder of Unicover Corporation. This painting originally appeared on the Fleetwood First Day Cover for the 33c Assassin Bug Classic Collection Series stamp issued October 1, 1999. Belonging to the order Heteroptera, some 4,000 species of the Assassin Bug are known to exist. Widespread throughout the world, they are most commonly found in tropical and subtropical areas. Most Assassin Bugs live outdoors, residing on trees and flowers or beneath stones. They can also be found indoors on old walls and in outhouses. Ranging in size from a few millimeters to three or four centimeters, Assassin Bugs are usually black or dark brown. Some, however, are brightly colored. Each is characterized by a narrow head connected to the body by a thin neck. The Assassin Bug derives its name from the speed and efficiency it displays when grabbing and poisoning prey. First, the Assassin Bug's curved beak pierces the victim's body. Next, a highly toxic saliva is injected that dissolves the muscles and tissues. The Assassin Bug then uses its beak like a straw to suck up the liquefied substance. Depending on the size of the prey, the Assassin Bug may live off it for days or weeks. After such a meal, the deadly predator may double its body weight. Some species have been known to attack humans, causing painful bites and spreading debilitating disease. Size: 14.25 x 11.75 in. Unframed. (B16506)
