Lesser Brown Scorpion

Lesser Brown Scorpions, or Isometrus maculates, can be classified as one of the members of the class Scorpionida, phylum Arthropoda. They live in tropical areas worldwide especially in Hawaii, located on Oahu, Kauai, Maui, and the big island itself.

They have a crablike appearance with long, fleshy tails made of five segments ending in a bulbous sac. The pedipalps (pincers) look like large claws, and its small jaws are partly hidden at the carapace, which covers the thorax. It also has four pairs of clawed legs.

Its life span usually reaches three to five years, which is normal for many of this species. Like most other scorpions, they go through courtship rituals. Their young are born alive, since females do not lay eggs. Immature scorpions stay on their mother's back until their first molt.

Its stinger is at the tip of the tail, attached to a bulbous organ that contains a venom-secreting gland. When injecting poison into the prey, it makes a quick, spring-like flick of the tail. The sting moves upward when the tail is extended but it goes down when in defense or attack mode. The act of stinging is repeated quickly which lessens the chances of survival for the victim since great quantities of poison will circulate throughout the entire body of the prey.

The Lesser Brown Scorpion is nocturnal, and feeds on creatures such as spiders, millipedes, or even small rodents.
