Centruroides nigrescens is a medium to large bark scorpion, native to southern Mexico and parts of Central America, where it inhabits tropical forests, scrublands, and human-modified environments. It is typically dark brown to nearly black. Like other Centruroides species, it is nocturnal, commonly sheltering during the day under bark, rocks, or debris and emerging at night to actively hunt insects and other arthropods. Its venom is medically significant, capable of causing intense pain and neurotoxic symptoms in humans, though severe reactions are uncommon and the species plays an important ecological role as an effective predator controlling insect populations.
Centruroides nigrescens
Description
• Centruroides nigrescens is a scorpion in the family Buthidae. It has the characteristic elongated body, slender pincers, and segmented tail ending in a venomous stinger typical of its genus. Its colouration is generally dark brown to blackish, although tones and markings can vary. Like other Centruroides scorpions, it relies on sensory hairs and vibrations to detect prey and navigate its surroundings.
Range
• Centruroides nigrescens is present in Zihuatanejo, Guerrero, Mexico. It is a Mexican species associated with western or southern parts of the country.
Habitat
• This species inhabits terrestrial environments where it can find shelter and prey. Scorpions of the genus Centruroides commonly hide beneath rocks, bark, fallen wood, and debris, and some use crevices in buildings or other structures. They are primarily nocturnal and emerge at night to hunt.
Diet
• Centruroides nigrescens is a carnivore that feeds mainly on insects, spiders, and other small arthropods. It seizes prey with its pincers and may use its venomous sting to subdue it. It may also be preyed upon by larger arthropods, reptiles, birds, and small mammals.
