Georissus Costatus
''Georissus'', also called minute mud-loving beetles, is the only genus in the beetle family Georissidae (or Georyssidae). They are tiny insects living in wet soil, often near water. They are found on every continent except Antarctica. Characteristics Georissidae are small beetles (length 1–2 mm). They have a broadly oval body whose outline is more or less interrupted between the pronotum and the elytra. The head and pronotum are granulate, the prosternum is rudimentary, without intercoxal processes. The anterior coxae and trochanters are fused. The basal ventrite is very large. Ecology Species are generally found within mud and sand at the periphery of rivers and streams, but also occur in tropical rainforest leaf litter. Species of ''Georissus'' are predators on invertebrates, and under laboratory conditions sometimes engage in cannibalism. Species within the genus are known for their habit of psammophory (actively covering their elytra with sand or mud) which help ...

François-Louis Laporte, Comte De Castelnau
François-Louis Nompar de Caumont Laporte, comte de Castelnau (born ''François-Louis Nompar de Caumont La Force''; 24 December 1802 – 4 February 1880) was a French naturalist, known also as François Laporte or Francis de Castelnau. The standard author abbreviation Castelnau is used to indicate him when citing a botanical name and zoological names other than insects. Laporte is typically used when citing an insect name, or Laporte de Castelnau. Life Born in London, Castelnau studied natural history in Paris. From 1837 to 1841 he traveled in the United States, Texas, and Canada. He visited Middle Florida from November 1837 until March 1838, publishing "Essai sur la Floride du Milieu" in 1843. In Canada he studied the fauna of the Canadian lakes and the river systems of Upper and Lower Canada (roughly corresponding to the modern provinces of Ontario and Quebec) and of the United States. Castelnau, a French savant, was sent by Louis Philippe, in 1843, with two botanists and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
