Oechalia schellenbergii is a species of bug from the subfamily Asopinae , which belongs to the family of stink bugs (Pentatomidae).

features

The gray-brown bugs have a very variable appearance. They each have a pointed thorn on the sides of the pronotum. The lower end of the label (scutellum) is brightly colored. The body length varies between 7.5 and 12 millimeters.

Occurrence

Oechalia schellenbergii is one of the most widespread predatory insects in Australia (including Tasmania ), New Zealand, and Polynesia . The bug species is found on various islands in the South Pacific. These include Fiji , Kiribati , Wake , the Pitcairn Islands , the Society Islands and the Tuamotu Archipelago .

Way of life

The bugs predatory feed on arthropods . Among the prey include caterpillars such as Helicoverpa armigera ( Helicoverpa armigera ), budworm , Loxostege affinitalis , Selidosema suavis , Anomis planalis , Earias huegeli , Phalaenoides glycine , Papilio anactus , Levuana iridescens and the small cabbage white butterfly ( Pieris rapae ). The bugs also prey on leaf beetles and their larvae. The beetle species affected include Chrysolina gemellata , Chrysolina hyperici , Chrysolina quadrigemina , Paropsis charybdis and Poneridia semipullata . The bugs are often found in cotton fields in the summer months from December to February. The females lay about 200 eggs in their lifetime. The development from oviposition to a fully grown bug takes about 3 weeks.
