🦂 Asian Forest Scorpion Care – Enclosure, Food, Humidity & Breeding

The Heterometrus Spinifer, otherwise sometimes also known as the Thai Black, Malaysian Forest Scorpion or the Asian Forest Scorpion, can be found in the southern parts of Asia (SEA). They are primarily found in countries like Vietnam, Cambodia, Thailand and Malaysia. These species of tarantulas grow as big as 5 inches (14 cm). With its very distinctive looks, the grey green reflections on their shiny black bodies. The Asian forest scorpion can make a very attractive pet, but its aggressive nature might ward off some terrified beginner hobbyist. Although stings from the Heterometrus Spinifer are not lethal, they can cause very severe pain and irritation. Numbness in the afflicted area can also occur. These are generally very easy to care for scorpions if the right steps are taken.

Temperature and Humidity

These species of tarantulas thrive in higher temperatures and humidity. Enclosure should be maintained at around room temperature (75° – 90 °F). With humidity ranging from 75 – 80%.


The Malaysian Forest Scorpion does well under humid conditions. They can be kept in a 2 1/2 to 15-gallon terrarium depending on the number of scorpions. A substrate of damp sand and peat moss with a top layer of cypress mulch, about 3″ deep. Also provide a shallow, wide water dish. A sheet of cork bark or similar shelter should be added to the Malaysian Forest Scorpion’s enclosure.

Food and Feeding

This scorpion feeds on large insects such as crickets, locusts and even small mice. Feed large scorpions a diverse diet consisting of adult crickets, grasshoppers, Tenebrio larvae, and only occasional feedings (once or twice a month) of mice. This variety more closely mirrors the diet of this scorpion nature and will keep them healthy.


Typically scorpions are loners, but like the Emperor Scorpions, this scorpion is a bit of an exception. Adults can be kept in groups of three or more. They can get into occasional scraps, and it is usually over a cricket. So be sure they are given enough food. It also helps to provide more hiding places than you have scorpions.


Females are often bulkier and have thinner pincers than the males. These differences, however, can be subtle. The pectines on the underside of scorpions can be inspected to give the you an idea of their scorpion’s sex. Place the scorpion in a clear plastic tub and hold it up to inspect the underside of the scorpion. Typically, males have longer combs on their pectines and females have shorter and often fewer combs on their pectines.

The male quickly grasps the pincers of the female and begins a shaking action known as “juddering”. Then, after a short shoving match, the male deposits a spermatophore onto the substrate and positions the female over the packet of sperm. The female lowers her abdomen and picks up the spermatophore into her genital opening. The two separate and often beat a hasty retreat in opposite directions.
