Scorpions in Captivity – An Overview of Popular Species: Asian Forest Scorpions, Genus Heterometrus

Hello, Frank Indiviglio here.

Note:  Please see Scorpions in Captivity – An Overview of Popular Species, Part I for general natural history and captive husbandry information.

Asian Forest Scorpions, Heterometrus spp.

Several species that superficially resemble emperor scorpions are sometimes available in the trade.  Known collectively as Asian forest scorpions and hailing from Southeast Asia, the most commonly seen is Heterometrus spinifer.  Like the emperor, it is jet black in color, but the claws have fewer spikes and its maximum size is 6 inches. 

Basic Care

I keep Heterometrus in much the same way as I have described for emperor scorpions (Please see Scorpions in Captivity – An Overview of Popular Species: The Emperor Scorpion, Pandinus imperator).  Like their African cousins, Asian forest scorpions are also quite social…a group of 10 that I housed together in an exhibit at the Bronx Zoo co-existed for years without incident.  They seem to be quite temperature sensitive, and are best maintained at 78-85 F.  The gestation period is 5-8 months and sexual maturity is reached in 1-3 years.

Asian forest scorpions are somewhat more high-strung than emperors, and sting readily.  Heterometrus spinifer is not considered dangerous to healthy adults, but the closely related H. swammerdami of India (which, at 10-12 inches in length, is among the world’s longest scorpions) has reportedly caused fatalities.

Asian forest scorpions and emperor scorpions are both classified within the Family Scorpionidae.  Further information and a complete listing of all related species is available at http://www.ub.ntnu.no/scorpion-files/scorpionidae.php.

Please write in with your comments and questions…suggestions as to other species you would like to read about would be most appreciated.  Thanks, until next time, Frank Indiviglio.

    I have a female scorpian sold to me as an asian forest scorpian. Yes it looks like the pictures but has dabs of white all over it`s body. I keep a wide range of animals from the bearded and asian dragons (lizards) to an african grey parrot. I always research my animals fully as a keeper I think it is my duty. But the scorpian it seams a bit more difficult to research, was not sure about vitamins but what you say makes good sense and will do like wise thank you. One thing though I found her more aggresive with her claws and as yet has not attacked my feeding tongs with her sting. No I ain`t daft enough to put my hand in.

    Hello Victor, Frank Indiviglio here. Thanks for your kind words and interest in our blog.

    My compliments on taking the time to research the animals in your collection…we certainly could use more of that! We know very little about the specific vitamin/mineral needs of scorpions – far less even than is known for reptiles and amphibians. Most of what seems to hold true has emerged over the years through trial and error, correspondence between interested people and comparisons with related, better-studied species.

    Your safest course of action would be to provide as much dietary variety as is possible, as described in the article you referenced. Forest scorpions likely take dozens of prey species in the wild; although many scorpions get by, often for years, on a cricket-based diet, I have noticed a definite difference in the overall health, vigor and breeding potential of animals maintained on varied diets.

    Your food animals should also be fed a balanced diet before being offered to animals in your collection…please let me know if you need any further information on that topic.

    Good luck, enjoy and please keep me posted.

    Best regards, Frank Indiviglio.

    Yes I have fed crickets & meal worms vitamins with their fruit & and veg` when gut loading them for my lizards. Also now trying other foods for the scorpian such as wood lice, worms, and other animals that I feel they may encounter in the wild. Thanks again for your help.

    Hello Victor, Frank Indiviglio here. Thanks for taking the time to write back.

    Great idea…scorpions really do take quite a wide range of prey, and providing such in captivity goes a long way in keeping them in good health. When you have a chance, please let me know what sort of invertebrates your scorpions accept.

    Enjoy, good luck and please keep me posted.

    Best regards, Frank Indiviglio.

Being born with a deep interest in animals might seem unfortunate for a native Bronxite , but my family encouraged my interest and the menagerie that sprung from it. Jobs with pet stores and importers had me caring for a fantastic assortment of reptiles and amphibians. After a detour as a lawyer, I was hired as a Bronx Zoo animal keeper and was soon caring for gharials, goliath frogs, king cobras and everything in-between. Research has taken me in pursuit of anacondas, Orinoco crocodiles and other animals in locales ranging from Venezuela’s llanos to Tortuguero’s beaches. Now, after 20+ years with the Bronx Zoo, I am a consultant for several zoos and museums. I have spent time in Japan, and often exchange ideas with zoologists there. I have written books on salamanders, geckos and other “herps”, discussed reptile-keeping on television and presented papers at conferences. A Master’s Degree in biology has led to teaching opportunities. My work puts me in contact with thousands of hobbyists keeping an array of pets. Without fail, I have learned much from them and hope, dear readers, that you will be generous in sharing your thoughts on this blog and web site. For a complete biography of my experience click here.
