Lesser Brown Scorpion

Natural history and identification

Isometrus maculatus is a scorpion, with grasping pincers and a segmented tail ending in a sting. Its reproductive biology has been studied directly: females can produce successive broods without mating again between every brood. That observation should not automatically be described as parthenogenesis, because repeated births after insemination do not establish reproduction without fertilization. The primary study concerns the species’ reproductive capacity; it does not establish brood timing, litter size, or seasonal reproduction in a wild Kauaʻi population.
