Gastrophysa Viridula
''Gastrophysa viridula'', known as the green dock beetle (note: the similar '' Gastrophysa cyanea'' in North America is also called the green dock beetle), green dock leaf beetle or green sorrel beetle, is a species of beetle native to Europe. Description The length of the green dock beetle varies between sexes, with the males being 4 mm and the females being 7 mm. During the mating season, females have enlarged abdomens. Both sexes are green with a metallic shimmer, which, depending on the light, can be gold green, blue, purple, violet, or red. The legs of this species also shimmer a metallic green, and are strongly built. The antennae are serrated and are medium in length. Subspecies *''Gastrophysa viridula pennina'' (Weise, 1882) *''Gastrophysa viridula viridula'' (De Geer, 1775) Distribution and habitat The green dock beetle is commonly found in central Europe, also common and widespread in Britain.

Gastrophysa Polygoni
''Gastrophysa polygoni'' is a species of leaf beetle in the subfamily Chrysomelinae. It was described by Carl Linnaeus in 1758. The species can be up to 5mm long and is green-blue in colour.

In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the cre ... is orange and the wing cases are a metallic green, and the beetle can be seen in spring and summer.

Gastrophysa Cyanea
''Gastrophysa cyanea'', the green dock beetle (note: ''Gastrophysa viridula'' in Europe is also sometimes called the green dock beetle), is a species of leaf beetle in the family Chrysomelidae 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 .... It is found in North America. ''G. cyanea'' is 4-5 mm and metallic green. Females can be distinguished by their swollen abdomens prior to egg laying. They emerge in spring and commonly feed on curly dock. Some pinned specimens will turn metallic blue.

Physogastrism
Physogastrism or physogastry is a characteristic of certain arthropods (mostly insects and mites), where the abdomen is greatly enlarged and membranous. The most common examples are the "queens" of certain species of eusocial insects such as termites, bees and ants, in which the abdomen swells in order to hold enlarged ovaries, thus increasing fecundity. This means that the queen has the ability to hold more and produce more eggs at one time. Physogastric queens produce an enormous number of eggs which can account for a significant amount of their body weight. In the termite species '' Macrotermes subhyalinus'', eggs can make up a third of their body weight, and a 15-gram queen can produce up to 30 eggs per minute. The physogastric queens' egg production is supported by oocyte proteins supplied by the "queen body fat." In termites Physogastrism in termites presents itself in quite an unusual manner. Unlike most physogastric insects, the queen termite is able to increase its size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Charles De Geer
Baron Charles de Geer (the family is usually known as De Geer with a capitalized "De" and is pronounced "de yer"); Finspång in Risinge 30 January 1720 – Stockholm 7 March 1778) was a Swedish industrialist and entomologist. Life De Geer, who came from a family with strong Dutch connections, grew up in Utrecht from the age of three. He returned to Sweden at the age of 19. He had inherited the entailed manor and important iron-works of Leufsta (Lövsta) in Uppland from his childless uncle and namesake and would substantially increased the wealth of the estate. Ever since he had received a present of some silk worms at the age of eight, he had an interest in entomology and became a respected amateur entomologist at an early age. His major work was the ''Mémoires pour servir à l'histoire des insectes'' (eight volumes, 1752-1778). He was elected a member of the Royal Swedish Academy of Sciences already in 1739, at the age of nineteen, and a corresponding member of the Fren ...
