The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. [2] A few very large genera (Ananteris, Centruroides, Compsobuthus, or Tityus) are known, but a high number of species-poor or monotypic ones also exist. [2] New taxa are being described at a rate of several new species per year. [2]
It excavates a vertical burrow around 18 cm (7 in) long, generally located at the base of a tuft of grass or among multiple tufts. The scorpion takes 2–3 nights to complete this, using its pincers to loosen the ground and then pedipalps and pincers as spades to carry the soil away. [4] It eats dung beetles, which fall into its burrow. [4]
