''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.〔Stol 2005〕 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.〔Pinto-da-Rocha ''et al.'' 2007: 375〕 Its second pair of legs is as long as 35 mm.〔Pinto-da-Rocha ''et al.'' 2007: 494〕 Its prominent pair of eyes is equipped with a spiny "crown". ''M. diadema'' was shown to feed on chironomid flies.〔Pinto-da-Rocha ''et al.'' 2007: 312〕 The gregarines ''Actinocephalus megabuni'' and ''Doliospora repelini'' (Eugregarinorida), and the mite ''Leptus beroni'' were found to parasitize on this species.〔Pinto-da-Rocha ''et al.'' 2007: 342,344〕 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.〔Pinto-da-Rocha ''et al.'' 2007: 289〕 The mainly parthenogenetic〔Stol 2005〕 ''M. diadema'' lays three batches of eggs per year, with about 30 eggs per batch that are deposited among leaf litter or on the soil.〔Pinto-da-Rocha ''et al.'' 2007: 431〕 The larvae, like many in the suborder Eupnoi, have an egg tooth.〔Pinto-da-Rocha ''et al.'' 2007: 464〕 Males have 28 chromosomes.〔Pinto-da-Rocha ''et al.'' 2007: 268〕 ==Footnotes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Megabunus diadema」の詳細全文を読む スポンサード リンク
