Megabunus diadema is a species of harvestman widely distributed in Europe, where it has been found in Iceland, Faroe Islands, Western Norway, Great Britain, Western France, Belgium and Northern Spain. Johan Christian Fabricius ( January 7, 1745 - March 3, 1808) was a Danish Entomologist and economist In Scientific nomenclature, synonyms are different Scientific names used for a single Taxon. Harvestmen are eight-legged Invertebrate animals belonging to the order Opiliones (formerly Phalangida) in the class Arachnida in the subphylum Iceland, officially the Republic of Iceland ( ( Ísland or Lýðveldið Ísland ( The Faroe Islands or Faeroe Islands or simply Faroe(s or Faeroes (Føroyar meaning " Sheep Islands" Færøerne Old Norse Norway ( Norwegian: Norge ( Bokmål) or Noreg ( Nynorsk) officially the Kingdom of Norway, is a Constitutional See also Kingdom of Great Britain Great Britain (Breatainn Mhòr Prydain Fawr Breten Veur Graet Breetain is the larger of the two main islands This article is about the country For a topic outline on this subject see List of basic France topics. The Kingdom of Belgium is a Country in northwest Europe. It is a founding member of the European Union and hosts its headquarters as well as those Spain () or the Kingdom of Spain (Reino de España is a country located mostly in southwestern Europe on the Iberian Peninsula.

It is commonly found among moss and lichens, and has a cryptic coloration that blends with this habitat, rendering it almost invisible when it is not moving. Mosses are small soft Plants that are typically 1–10 cm (0 Lichens (ˈlaɪkən or /lɪtʃən/ are symbiotic associations of a Fungus (the mycobiont with a photosynthetic partner (the photobiont also known as [2] Its second pair of legs is as long as 35 mm. The Millimetre ( American spelling: millimeter, symbol mm) is a unit of Length in the Metric system, equal to [3] Its prominent pair of eyes is equipped with a spiny "crown".
M. diadema was shown to feed on chironomid flies [4]. Chironomidae (informally known as chironomids or non-biting Midges) are a family of Nematoceran flies with a global distribution
The gregarines Actinocephalus megabuni and Doliospora repelini (Eugregarinorida), and the mite Leptus beroni were found to parasitize on this species. The gregarines are a group of Apicomplexan protozoa classified as the Gregarinasina or Gregarinea Mites, along with Ticks belong to the subclass Acarina (also known as Acari and the class Arachnida Mites are among the most diverse and successful Parasitism is a type of symbiotic relationship between Organisms of different Species.

During a study of woodland in Scotland, they were found to be most active during March, June to July and December; in montane regions of Wales they only occurred in August, while they were found all year round in English woodland, with a peak from May to August. Scotland ( Gaelic: Alba) is a Country in northwest Europethat occupies the northern third of the island of Great Britain. England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland [6]
The mainly parthenogenetic[1] M. Parthenogenesis (from the Greek παρθένος parthenos, "virgin" + γένεσις genesis, "creation" is an asexual form diadema lays three batches of eggs per year, with about 30 eggs per batch that are deposited among leaf litter or on the soil. [7] The larvae, like many in the suborder Eupnoi, have an egg tooth. The Eupnoi are a suborder of Harvestmen, with more than 200 genera and about 1700 described species In some egg -laying Animals the egg tooth is a small sharp cranial protuberance used by Offspring to break or tear through the egg's surface during [8]
Males have 28 chromosomes[9]. A chromosome is an organized structure of DNA and Protein that is found in cells.
