The shape of these insects resembles both crickets and cockroaches, hence the name Blattida. Body length 13-30 mm. Wingless; filamentous antennae, small compound eyes, no single eye. The mouthparts are chewing and the palate is well developed. There are spikes at the end of the male's abdomen. All known species live in alpine rocks, rotten wood and soil at altitudes above 1,000 meters. It is a carnivorous insect and a rare species.

There are only 29 species and subspecies in 1 family, 4 genera and subspecies known in this order. Its distribution area is narrow and is currently limited to the west of the Rocky Mountains in North America and high latitudes such as northeastern Asia and southern Siberia. There is only one species known in my country. It was first discovered in Changbai in Northeast China in 1986 and named Galloisiana sinensis Wang (after Chen Ruijin's picture). In 1988, it was listed as a first-level protected wild animal in my country.

The characteristics of this order can be summarized as follows: flat-bodied and wingless Blattida, with male tarsus and terminal spines on the abdomen; well-developed upper jaw and large prothoracic body; individuals are rare in living fossils.
