Thorellius tekuani is a medium-sized bark scorpion, native to southern Mexico, where it inhabits tropical and subtropical forests. It is typically yellowish to light brown It is arboreal and nocturnal, often sheltering under loose bark, in tree crevices, or among vegetation during the day and emerging at night to hunt insects and other small arthropods. Its venom is considered mild and not medically significant to humans, producing effects similar to a bee sting, while ecologically the species plays an important role as a predator regulating insect populations within forest ecosystems. Lighter coloured immature scorpions are vulnerable and reside on their mother's back for about 4 weeks until they reach their molting stage. They then shed their exoskeleton for a larger, more durable one and leave their mother after the process is complete.
