Hagenomyia Tristis

	Hagenomyia Tristis ''Hagenomyia tristis'' is an African antlion species. It is known as the gregarious antlion as it is often found in swarms in long grass in the shade of trees. The range of this species extends from eastern South Africa to Cameroon and Ethiopia; it is also found in Madagascar. The larvae build sand pit traps to capture prey. This species is believed to be the mimic of '' Banyutus lethalis'', with both species commonly swarming together.

picture info	Francis Walker (entomologist) Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance. Between June 1848 and late 1873 Walker was contracted by John Edward Gray Director of the British Museum to catalogue their insects (except Coleoptera) that is Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Walker largely accomplished this and (Edwards, 1870) wrote of the plan and by implication those who implemented it “It is to him raythat the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, the publication of which beg ...

picture info	Antlion The antlions are a group of about 2,000 species of insect in the neuropteran family Myrmeleontidae. They are known for the predatory habits of their larvae, which mostly dig pits to trap passing ants or other prey. In North America, the larvae are sometimes referred to as doodlebugs because of the marks they leave in the sand. The adult insects are less well known due to their relatively short lifespans compared to the larvae. Adults, sometimes known as antlion lacewings, mostly fly at dusk or after dark and may be mistakenly identified as dragonflies or damselflies. Antlions have a worldwide distribution. The greatest diversity occurs in the tropics, but a few species are found in cold-temperate locations, one such being the European ''Euroleon nostras''. They most commonly occur in dry and sandy habitats where the larvae can easily excavate their pits, but some larvae hide under debris or ambush their prey among leaf litter. Antlions are poorly represented in the fossil rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

Both species fly gregariously through long grass and can be collected together. The larvae of ''B. lethalis'' are non-pit building, whereas those of ''H. tristis'' are pit-builders.

picture info	Insects Of Africa Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
