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.
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined.
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, Asia to the east, and the Mediterranean Sea to the south. It comprises the westernmost part of Eurasia.
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.
Viola riviniana, the common dog-violet, is a species of the genus Viola native to Eurasia and Africa. It is also called wood violet and dog violet. It is a perennial herb of woodland edges, grassland and shady hedge banks. It is found in all soils except acid or very wet.
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.
Elasmucha grisea, common name parent bug, is a species of shield bugs or stink bugs belonging to the family Acanthosomatidae. The term parent bugs includes also the other species of the genus Elasmucha and some species of the family Acanthosomatidae.
The wheel bug is a species of large assassin bug in the assassin and kissing bug family Reduviidae. The species is one of the largest terrestrial true bugs in North America, reaching up to 1.5 inches (38 mm) in length in their adult stage. They are sexually dimorphic, in that males are somewhat smaller than the females. A characteristic structure is the wheel-shaped pronotal armor. Wheel bugs prey on caterpillars and beetles, such as Japanese beetles, the cabbage worm, orange dogs, tent caterpillars, and the Mexican bean beetle, all of which they pierce with their beak to inject salivary fluids that dissolve soft tissue. Wheel bugs are most active in daylight, though they may engage in predatory behaviors at night in areas illuminated by lights. Because most of their prey are pests, wheel bugs are considered as beneficial.
Blissus leucopterus also known as the true chinch bug is a small North American insect in the order Hemiptera and family Blissidae. It is the most commonly encountered member of the genus Blissus, which are all known as chinch bugs. A closely related species is Blissus insularis, the southern chinch bug.
The green shield bug – Palomena prasina – is a European shield bug species in the family Pentatomidae. The name might equally apply to several other species in the tribe Nezarini, or if referred-to as a "green stink bug", it might more appropriately belong to the larger North American bug, Acrosternum hilare. 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.
The green stink bug or green soldier bug is a stink bug of the family Pentatomidae.
Dolycoris baccarum, the sloe bug, is a species of shield bug in the family Pentatomidae.
The Tingidae are a family of very small insects in the order Hemiptera that are commonly referred to as lace bugs. This group is distributed worldwide with about 2,000 described species.
Coreus marginatus is a herbivorous species of true bug in the family Coreidae. It is commonly known as the dock bug as it feeds on the leaves and seeds of docks and sorrels. It is a medium-sized speckled brown insect, between 13 and 15 mm long as an adult, with a broad abdomen. It occurs throughout Europe, Asia and northern Africa. It is often found in dense vegetation, such as hedgerows and wasteland.
Eurydema oleracea is a species of shield bug in the family Pentatomidae and is commonly known as the rape bug, the crucifer shield bug, the cabbage bug or the brassica bug.
Corythucha ciliata, the sycamore lace bug, is a species of lace bug in the family Tingidae that is associated with sycamore trees.
Oxycarenus lavaterae, common name lime seed bug, is a species of ground bug of the family Lygaeidae, subfamily Oxycareninae.
Himacerus mirmicoides, common name ant damsel bug, is a species of damsel bugs belonging to the family Nabidae, subfamily Nabinae.
Stagonomus venustissimus, common name woundwort shieldbug, is a species of shieldbug belonging to the family Pentatomidae, subfamily Pentatominae.
Heterotoma planicornis is a species of bug from Miridae family.
Eurygaster maura, also known as tortoise bug, is a species of true bugs or shield-backed bugs belonging to the family Scutelleridae.

Sehirus luctuosus, the Forget-me-not Bug, is a burrowing shieldbug belonging to the family Cydnidae. It is found from Europe to Central Asia.In Central Europe it is widespread and not uncommon. They are found in the Alps on sunny slopes up to almost 2000 meters above sea level.
Anthocoris nemoralis is a true bug in the family Anthocoridae. The species is native to Europe and is introduced in North America. It is a predator of aphids, spider mites and jumping plant lice, and is therefore used as a biological pest control agent.
Dysdercus koenigii is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton staining fungi as they do so.
