Thyreocoris scarabaeoides

Thyreocoris scarabaeoides is a species of shield bug found in Europe. It is small (3–4 mm.), nearly round and dark bronzy coloured. The surface is shining, glabrous and strongly punctured. The antennae are piceous, the scutellum not quite covering the corium and membrane. The legs are black with spinose tibiae and piceous tarsi. [1]

The nymphs and adults feed primarily on violets ( Viola ), but they are found on the ground under different plant species. Initially, the nymphs live in aggregations. Overwintering is under dry leaf and needle litter, under stones or in moss. Mating takes place from April, the egg laying mainly in May and June. The adult animals of the new generation can be found from late July or August. There is a single generation per year.

The Plecoptera are an order of insects, commonly known as stoneflies. Some 3,500 species are described worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger. Their modern diversity, however, apparently is of Mesozoic origin.

The adult green shield bug ranges in the colour of their backs from bright green to bronze, without any substantial markings. Green shield bugs are a very common shield bug throughout Europe, including the British Isles, and are found in a large variety of habitats, including gardens. They have been found as far north as 63° N latitude.

<i>Reduvius personatus</i> Species of true bug
