Platybunus Triangularis
''Rilaena triangularis'' is a species of the harvestman family Phalangiidae.Raspotnig, G., Schaider, M., Föttinger, P., Leutgeb, V., & Komposch, C. (2015). Benzoquinones from scent glands of phalangiid harvestmen (Arachnida, Opiliones, Eupnoi): a lesson from Rilaena triangularis. Chemoecology, 25(2), 63–72. https://doi.org/10.1007/s00049-014-0177-y It is sometimes considered to be in the genus '' Paraplatybunus'', in the subfamily Platybuninae. Description ''Rilaena triangularis'' is a harvestman that lives across Europe. This species was first described by Johann Friedrich Wilhelm Herbst in 1799, initially as ''Phalangium triangularis''. It was later renamed through recombination. Chemical defense When disturbed, ''Rilaena triangularis'' emits a strong-smelling secretion as a chemical defense. This fluid contains 1,4-benzoquinone, 1,4-naphthoquinone and caprylic acid. Range Occurrences of ''Rilaena triangularis'' have been recorded and aggregated in GBIF across Europe ...

Johann Friedrich Wilhelm Herbst
Johann Friedrich Wilhelm Herbst (1 November 1743 – 5 November 1807) was a German natural history, naturalist and entomologist from Petershagen, Minden-Ravensberg. He served as a chaplain in the Prussian army. His marriage in Berlin, 1770, with Euphrosyne Luise Sophie (1742–1805), daughter of the Prussian ''Hofrat'' Libert Waldschmidt, seems to have been childless. He was the joint editor, with Carl Gustav Jablonsky, of ''Naturgeschichte der in- und ausländischen Insekten'' (1785–1806, 10 volumes), which was one of the first attempts at a complete survey of the order Coleoptera. Herbst's ''Naturgeschichte der Krabben und Krebse'', released in installments, was the first full survey of crustaceans. Herbst's other works included ''Anleitung zur Kenntnis der Insekten'' (1784–86, 3 volumes), ''Naturgeschichte de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvestman
The Opiliones (formerly Phalangida) are an order of arachnids, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs (see below). , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their phylogenetic position within the Arachnida is disputed; their closest relatives may be camel spiders (Solifugae) or a larger clade comprising horseshoe crabs, Ricinulei, ...

Phalangiidae
The Phalangiidae are a family of harvestmen with about 380 known species. The best known is ''Phalangium opilio''. ''Dicranopalpus ramosus'' is a common introduced species in Europe. It is not to be confused with the harvestman family Phalangodidae, which belongs to the suborder Laniatores. Name The name of the type genus is derived from Ancient Greek ''phalangion'' "harvestman".

Chemical Defense
Chemical defense is a strategy employed by many organisms to avoid consumption by producing toxic or repellent metabolites or chemical warnings which incite defensive behavioral changes. The production of defensive chemicals occurs in plants, fungi, and bacteria, as well as invertebrate and vertebrate animals. The class of chemicals produced by organisms that are considered defensive may be considered in a strict sense to only apply to those aiding an organism in escaping herbivory or predation. However, the distinction between types of chemical interaction is subjective and defensive chemicals may also be considered to protect against reduced fitness by pests, parasites, and competitors. Repellent rather than toxic metabolites are allomones, a sub category signaling metabolites known as semiochemicals. Many chemicals used for defensive purposes are secondary metabolites derived from primary metabolites which serve a physiological purpose in the organism. Secondary metabolites pro ...
