Thyanta (Thyanta) custator is a Wanzenart from the family of stink bugs (Pentatomidae). In English, the bug is also known as the Red-shouldered Stink Bug ("red shouldered stink bug ").

features

The green or brownish colored 10 to 11 millimeter long bugs are externally very variable. They often have a pink horizontal stripe on the pronotum, the front sides of the pronotum and the lower end of the label (scutellum) are often pink. However, there are populations that lack these characteristics.

Occurrence

The bug species occurs in North and Central America. It is present and widespread across the continents in the United States and Canada.

Way of life

The polyphagous bugs have a wide range of host and fodder plants. In addition to many other plants , these include Prosopis , Baccharis , Bouteloua grasses, guayule and goldenrod ( Solidago ). The bugs cause damage to crops such as cotton , sorghum , soybeans and maize . That is why they are considered pests of economic importance in the United States .

Taxonomy

The species of the genus Thyanta have been revised several times. A subdivision of the bugs into Thyanta custator and Thyanta pallidovirens as well as the latter into 3 subspecies ( accerra , setosa and spinosa ), proposed by Herbert Ruckes in 1957, was later rejected by David Rider. According to the current opinion, only those populations occurring in California with missing thorns or spots on the underside of the abdomen belong to Thyanta pallidovirens .
