Conchuela Bug

Adults have been observed from June to October (McPherson and McPherson 2000).

This species is widely distributed in the United States. In Canada this species has been recorded in Alberta, British Columbia, North West territories and Saskatchewan (Scudder and Thomas 1987). In Alberta, most records are from the southern region, with one in the north (Peace River).

This species has straight or reflexed anterolateral margins of the pronotum. Green scutellum with pale orange to red apex and without median, longitudinal yellow stripe. The costal margin of the corium and connexivum pale orange to red. The rostrum on this species reaches the posterior edge of the metasternum. This species exhibits minute purple flecks on the membrane. The pygophore has a central prominence subtended laterally by a pair of smaller prominences. Length 13-19 mm.

The bugs appear to over-winter as adults, emerging in the spring to begin feeding and reproducing on wild hosts. This species will feed on stems and leaves but prefer immature seeds. As the wild hosts mature and dry, the bugs move to cultivated crops. The species appears to be bivoltine (McPherson and McPherson 2000).

This species attacks cultivated crops including cotton, beans, alfalfa, peaches, grapes, peas, tomatoes, pepper, squash and corn (McPherson and McPherson 2000). In the United States this species has been found on wild hosts including blackberries (Rubus lacintus) and strawberries (Fragaria spp.) (Fish and Alcock 1973). This species has been reported as injuring peach fruit in British Columbia (Scudder and Thomas 1987).

Chlorochroa ligata, the conchuela bug, is a species of stink bug in the family Pentatomidae. It is found in Central America and North America.
