Plagiodera Versicolora
''Plagiodera versicolora'' is a species of leaf beetle (subfamily Chrysomelinae) in the genus ''Plagiodera''. Description ''Plagiodera versicolora'' grows to 2.5 - 4.8 mm in length and is metallic blue or green, occasionally purplish to black in colour. Habitat ''Plagiodera versicolora'' lives in various habitats, but usually near water. Adults feed on leaves and pollen of willow and poplar trees, especially '' Salix fragilis'' ('crack willow'). It is predated by the shieldbug ''Zicrona caerulea'', several ladybird species and the larva of a hoverfly (''Parasyrphus'' sp.). Life cycle Adults overwinter under logs, loose bark and among vegetable litter near the host plant and become active during April. Fully developed larvae may be found from June onwards and pupation occurs under the leaves of the host plant. Freshly emerged adults occur from mid-July and fly in hot weather, occasionally found far from their hosts, especially along river margins. Distribution It is fairly co ...

Leaf Beetle
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines the Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, f ...

Chrysomelinae
The Chrysomelinae are a subfamily of leaf beetles (Chrysomelidae), commonly known as broad-bodied leaf beetles or broad-shouldered leaf beetles. It includes some 3,000 species around the world. The best-known member is the notorious Colorado potato beetle (''Leptinotarsa decemlineata''), an important agricultural pest. Description Adults of Chrysomelinae are beetles with the following features: antennae inserted on or adjacent to anterior edge of head; inner face of each mandible with large membranous prostheca; each wing with only one anal cell (sometimes the wings are reduced or absent); metendosternite lateral arms without lobes; femora without internal spring sclerite; tibial spurs absent; tarsi without bifid setae; stridulatory mechanism absent; male aedeagus without tegminal ring and the testes not fused within a common membrane; female kotpresse absent.

Parasyrphus
''Parasyrphus'' is a genus of hover fly found in the holarctic area of the world including species like '' Parasyrphus tarsatus'' located in some very northern areas.

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest.

The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Beetles Of Europe
Beetles are 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 described 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, with estimates suggesting that there are between 0.9 and 2.1 million total species. 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 (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
