Cermatulus nasalis is a type of bug from the subfamily Asopinae , which belongs to the family of stink bugs (Pentatomidae). The bug is also known as the Glossy Shield Bug ("shiny shield bug ").

features

The red-brown or brownish shiny bugs reach a body length of 12 to 15 millimeters. They have an oval shape. The sides of the pronotum form obtuse angles. The dorsal surface has a fine yellow dot. The lower end of the label (scutellum) is usually brightly colored. The connexive (part of the abdomen that is visible on the side) is piebald dark brown-yellow.

Occurrence

Cermatulus nasalis occurs in Australia and New Zealand.

Taxonomy

There are three subspecies:

Cermatulus nasalis hudsoni ( Westward , 1953) - endemic to New Zealand
Cermatulus nasalis nasalis ( Westwood , 1837) - in Australia and New Zealand
Cermatulus nasalis turbotti Westward , 1950 - endemic to New Zealand

Way of life

The bugs predatory feed on various arthropods . Their prey include the leaf beetle Galerucella semipullata and Paropsis charybdis , the weevil Gonipterus scutellatus , the cicada species Melampsalta cruentata and the sawfly Caliroa cerasi and Caliroa limacina . Furthermore, the following caterpillars are captured: Crambus vittellus , Asaphodes megaspilata , Selidosema suavis , Venusia verriculata , black cutworm ( Agrotis ipsilon ), Helicoverpa armigera ( Helicoverpa armigera ), Mythimna separata , Persectania Aversa , Phalaenoides glycine , monarch butterfly ( Danaus plexippus ), Vanessa gonerilla , Epiphyas postvittana , Tortrix excessana and Tanaoctena dubia . In the summer months, the bugs stay on various crops such as alfalfa ( Medicago sativa ), seed flax ( Linum usitatissimum ) and cotton , where they lurk for prey. The species forms one generation per year. The development, beginning with the oviposition to the full-grown bug, takes about three weeks.
