Scymnus suturalis is a species of beetle in family Coccinellidae. It is found in the Palearctic - Europe, North Africa, European Russia, the Caucasus, Siberia, the Russian Far East, Belarus, Ukraine, Moldova, Transcaucasia, Western Asia, Mongolia, North America (introduced to the United States). [2] [3]
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 70,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
Coccinellidae is a widespread family of small beetles ranging in size from 0.8 to 18 mm. The family is commonly known as ladybugs in North America, and ladybirds in Britain and other parts of the English-speaking world. Entomologists widely prefer the names ladybird beetles or lady beetles as these insects are not classified as true bugs.
It is a tiny (2mm. -2.5 2mm.) ladybird. The elytra which bear long, mainly backward-pointing hairs are red or chestnut brown usually with a dark brown mark behind the scutellum and extending along the median. It is common. In Central Europe it is a forest species which feeds on Coccoidea—it is associated with the scale Chionaspis salicis . [4] S. suturalis occurs in conifer (especially Pinus sylvestris and other Pinus species) and mixed forests, also in marshes, gardens, and parks. In Russia and Poland, it feeds on Adelgidae and other aphids on Pinus, less frequently, on Betula pendula and other Betula species and Ligustrum vulgare . [5] [6] It was also found under flakes of bark, in moss on the trunks, and in the litter of coniferous trees.
Central Europe is the region comprising the central part of Europe. Central Europe occupies continuous territories that are otherwise sometimes considered parts of Western Europe, Southern Europe, and Eastern Europe. The concept of Central Europe is based on a common historical, social, and cultural identity.
The Adelgidae are a small family of the Hemiptera closely related to the aphids, and often included in the Aphidoidea with the Phylloxeridae or placed within the superfamily Phylloxeroidea as a sister of the Aphidoidea within the infraorder Aphidomorpha. The family is composed of species associated with pine, spruce, or other conifers, known respectively as "pine aphids" or "spruce aphids". This family includes the former family Chermesidae, or "Chermidae", the name of which was declared invalid by the ICZN in 1955. There is still considerable debate as to the number of genera within the family, and the classification is still unstable and inconsistent among competing authors.
Betula pendula, commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe it is only found at higher altitudes. Its range extends into Siberia, China and southwest Asia in the mountains of northern Turkey, the Caucasus and northern Iran. It has been introduced into North America, where it is known as the European white birch, and is considered invasive in some states in the United States and in parts of Canada. The tree can also be found in more temperate regions of Australia.
