Life Cycle
Platyarthrus hoffmannseggii is a myrmecophylous isopod, which means it lives in ant nests. Blind and it is not clear why ants don't eat them. It's not the only species from the Platyarthrhus genus, but hoffmannseggi is the most frequent world-wide.

Genus: Platyarthrus Brandt, 1833
species: hoffmannseggii Brandt, 1833
