  sand cockroaches, desert cockroaches

  Arenivaga is a genus of sand cockroaches in the family Corydiidae, comprising approximately 48 species distributed across the southwestern United States, Florida, and Mexico. These insects are highly adapted to arid environments, inhabiting sandy soils and dunes with moisture content below 1%. The genus exhibits extreme sexual dimorphism, with winged males and wingless, fossorial females that 'swim' through sand. A 2014 revision by Heidi Hopkins added 39 new species to the previously known nine, revealing a remarkable radiation in desert habitats.
