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.[3] Its second pair of legs is as long as 35 mm.[4] Its prominent pair of eyes is equipped with a spiny "crown".
M. diadema was shown to feed on chironomid flies.[5]
The gregarines Actinocephalus megabuni and Doliospora repelini (Eugregarinorida), and the mite Leptus beroni were found to parasitize on this species.[6]
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.[7]
The mainly parthenogenetic[2] 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.[8] The larvae, like many in the suborder Eupnoi, have an egg tooth.[9]
Males have 28 chromosomes.[10]
