Baccha Cognata
''Baccha'' is a genus of hoverflies in the subfamily Syrphinae. They are typically moderate sized with wasp-like bodies. Their larvae are predatory, often on aphids. Description This genus is extremely slender with a club shaped abdomen that is at least 25 times as long as its narrowest width They range in length from about 7 to 10 mm. The wings are either clear or have very faint brownish markings, have an alula that is much narrower than cell c at its base, a reduced anal angle, and small bare spots near the base, with faint clouding along The apical crossveins. The eyes have very short and sparse hairs, while its frons and face are mostly pollinose and black. The antennae are yellow to black and very short, with the scape at least as deep as it is long. The thorax has short hairs on its scutum, which is mostly shining lightly pollinose above and on the sides, which are either entirely black or with a few yellow margins. The scutellum is similarly colored, but with pile only as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baccha Elongata
''Baccha elongata'' is a species of hoverfly (or flower fly) in the genus ''Baccha''. Distribution and habitat ''Baccha elongata'' is present in most of Europe and in North America. Common and widely distributed throughout Great Britain, Britain and Ireland wherever there is suitable habitat though easily overlooked due to its unobtrusive nature. These hoverflies inhabit coniferous and deciduous forests, woodland, hedgerows, scrub and gardens Generally they prefer shady places low to the ground. Description ''Baccha elongata'' can reach a length of .J.K. LindseCommanster/ref> It is one of the smaller hoverflies, the wing length is around 4.5 to 8 mm. The long, very slender body of these hoverflies is unmistakable. They also differ from other hoverflies by their elongated, thin abdomen ending in club. This club-shaped abdomen is black with a yellow spot on the 3rd and 4th segments. Legs are brownish yellow. Forehead is brightly hairy. Members of the eristalinae, eristalin ...

Hoverfly Genera
Hoverflies, also called flower flies or syrphids, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae ( maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, specifically detritivores, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores, preying on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered crop pests, so the aphid-eating larvae of some hoverflies are economically and ecologically important. The larvae are potential agents for use in biological control, while the adults are pollinators. About 6,000 species in 200 genera have been described. Hoverflies are common throughout the world and can be found on all continents except Antarctica. Hoverflies are harmless to most mammals, though many s ...

Moses Harris
Moses Harris (15 April 1730 – 1787) was an English entomologist and engraver. Life and work Harris was encouraged in entomology from a young age by his uncle, a member of the Society of the Aurelians. In 1762 he became secretary of a second Society of Aurelians. He was a skilled artist, displaying some of his insect drawings at the Royal Academy in 1785. He drew and engraved illustrations for books including Dru Drury's ''Illustrations of Natural History'' (3 volumes, 1770–1782) and John Coakley Lettsom's ''The Naturalist's and Traveller's Companion'' (1772). Colour theory In "The Natural System of Colours" published in 1766, Harris discussed the multitude of colours that can be created using three "grand or principle" colours: red, yellow and blue. As a naturalist and an engraver, Harris focussed on the relationships between colours and how they are coded and created. He explained how three colours can be íntermixed, tinted and shaded to create 660 colours "materially, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
