Letrini

Letrini or Letrinoi or Letrina was a town of Pisatis in ancient Elis, situated near the sea, upon the Sacred Way leading from Elis to Olympia, at the distance of 180 stadia from Elis, 120 from Olympia. According to Greek mythology, it was said to have been founded by a son of Pelops. There was a tradition that said that the bones of Pelops - necessary, according to the oracle, for the Achaeans to conquer Troy - were at Letrini. Together with several of the other dependent townships of Elis, it joined Spartan king Agis II, when he invaded the territories of Elis; the townsmen of Letrini formed part of the Spartan army that fought at the Battle of Nemea in 394 BCE. Xenophon speaks of Letrini and Marganeis as Triphylian places, although they were on the right bank of the Alpheius; the Λετριναῖαι γύαι are mentioned by Lycophron.. In the time of Pausanias nothing remained of Letrini except a few houses and a temple of Artemis Alpheiaea, it remains doubtful whether this temple is the same as that mentioned by Strabo as located near the mouth of the Alpheius.

Letrini may be placed at the village and monastery of Agios Ioannis, between Pyrgos and the port of Katakolo, according to William Martin Leake, among many fragments of antiquity, a part of a large statue was found in the early 19th century.

Snow scorpionfly

Boreidae called snow scorpionflies, or in the British Isles, snow fleas are a small family of scorpionflies, containing only around 30 species, all of which are boreal or high-altitude species in the Northern Hemisphere. Recent research indicates the boreids are more related to fleas than to other scorpionflies, which renders the order Mecoptera paraphyletic if the order Siphonaptera is excluded from it; these insects are small, with the wings reduced to bristles or absent, they are somewhat compressed, so in fact some resemblance to fleas is noted. They are most active during the winter months, towards the transition into spring, the larvae feed on mosses; the adults will disperse between breeding areas by walking across the open snow, thus the common name. The males use their bristle-like wings to help grasp the female while mating; the body temperature, therefore activity level, of this scorpionfly depends on its absorption of short-wave and long-wave radiation rather than surrounding air temperatures.

The boundary layer of snow that the insect occupies has low thermal conductance, so the insect loses its own heat slowly here. This delicate balance between cold and heat means that the animal is killed by heat when held in a human hand; the cladogram of external relationships, based on a 2008 DNA and protein analysis, shows the family as a clade, sister to the Siphonaptera, more distantly related to the Diptera and Mecoptera. This list is adapted from the World Checklist of extant Mecoptera species, is complete as of 1997; the number of species in each genus is indicated in parentheses.
