Philhelius Pedissequus
''Philhelius pedissequus'' is a species of hoverfly. Prior to 2018, it was known under the genus name ''Xanthogramma'', a junior synonym. Etymology The Latin species name ''pedissequus'' means ''that follows on foot'', like an attendant. Distribution and habitat This uncommon species is present in most of Europe, in Western Siberia, in the Near East and in North Africa. It prefers grassland, open fields close to deciduous forest. Description ''Philhelius pedissequus'' can reach a length of and a wing length of 7.25–9.75 mm.J.K. LindseCommanster/ref>Stuart Ball, Roger MorriBritain's Hoverflies: A Field Guide, Revised and Updated Second Edition/ref> These hoverflies have a black body, with two yellow lateral stripes on the thorax, and yellow markings on tergites two to five. The pairs of tergites 2 are wedge-shaped and considerably wide. Biology Flight period last from mid May through September, with a peak at the end of June. The adults feed on different flowers, f ...

Hoverfly Genera
Hover flies, also called flower flies or syrphid flies, 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, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Josef Mik
Josef Mik, also Joseph Mik (23 March 1839 in Zábřeh – 13 October 1900 in Vienna) was a Bohemian entomologist mainly interested in Diptera. He described many new species and made contributions to knowledge of the Diptera of Central Europe. Mik was the first dipterist to clarify the chaetotaxy of the legs. " On the legs I distinguish a front haeta and a hind-side ; an upper- and an under-side. When we imagine the leg stretched out horizontally and perpendicularly to the longitudinal axis of the body, the front-side is that which is turned towards the head, and the hind-sidethat turned towards the end of the body ; the upper- and under-side, in such a case, are self-understood."Mik, J. 1878 Dipterologische Untersuchungen Jahresber K.K. Akad. Gymnasium Vienna Mik was born in Zábřeh, Moravia. From 1871 to 1889 he was teacher at the Academic Gymnasium in Vienna. In 1889 he was given the Knight's Cross of the Order of Franz Joseph; he died in Vienna. Works * 1866 Beitrag zur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
