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.[1]

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.[2] Its second pair of legs is as long as 35 mm.[3] Its prominent pair of eyes is equipped with a spiny "crown".

M. diadema was shown to feed on chironomid flies [4].

The gregarines Actinocephalus megabuni and Doliospora repelini (Eugregarinorida), and the mite Leptus beroni were found to parasitize on this species. [5]

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.[6]

The mainly parthenogenetic[1] 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.[7] The larvae, like many in the suborder Eupnoi, have an egg tooth.[8]

Males have 28 chromosomes[9].
