Scorpion predation by arthropoda

    Despite their formidable armour, scorpions are known to suffer from parasitism by nematodes and ectoparasitism by acarians (pterygosomydae), are predated by theraposids (B vagans) and large centipedes, but very little is known about interactions with members of the order hemiptera.
    Reduviidae has proven to exploit morphological weaknesses of the scorpion armor: they insert their rostrum into the pleura between mesosoma's segments:

    Predation on the Scorpion Centruroides hentzi (Banks) (Scorpiones: Buthidae) by the Assassin Bug Microtomus purcis (Drury) (Insecta: Hemiptera: Reduviidae)

    Do you know any other examples? More interestingly, are there other arthropods preying on scorpions. What about pompilid wasps?

    Tarantulas will eat scorpions.

    Flies Sarcophaga dux and Megaselia scalaris were recorded as facultative parasites of scorpions.

    yes but those flys prey on almost any organism if they can get access to a festering wound, they aren't specialised on parasitising scorpions, let alone being a parasite in general.

    Scorpions fall prey to lots of animals mammals and birds mostly, as well as some other top arthropod predators like those assasin bugs, cannibalism happens as well.
    The question is, is there an animal out there that specialises exclusively on scorpions as prey or host?

    yeah, that is what word "facultative" stands for :meh:
    Yes, mites Pimeliaphilus isometri, Pimeliaphilus joshuae and Pimeliaphilus rapax, and most likely some other species.

    Funny thing, it actually seems that the most significant invertebrate predators of scorpions are other scorpions.

    I'm sure large centipedes often make short work of smaller scorpions.

    Ah i see, never heard that before.

    Got to read up on those mites. Thx.

    Scorpions, spiders, tarantulas, solifugids, and centipedes all prey on each other. Size differential seems to make a difference on the outcome (or rather predation is often a favorable opportunity) but in some instances the tables may even be turned on the predator. Then there are lizards, amphibians, birds, and small mammals too. But outside of these parasites (of which I only just read about here) and assassin bugs I have never heard of any arthropods that actually specialize on scorpion predation.

    Good post and interesting links, i know I'm going off track here but I recently gave a friend a hand to unbox an order (he owns a petshop) and a large phlogius was found dead the next morning but underneath it was a liocheles scorpion, did this scorpion kill this T or is it coincidence.
    Obviously there was still a scorpion that was overlooked in the display tank

    A Liocheles take down a large tarantula, my guess it was a coincidence. I imagine the tarantula would have simply pounced on the Liocheles which may not even possess the venom potency to kill a Phlogius. But then again I am not familiar with Liocheles.


    Luckily, Dor’s data told a clear story - the undisputed champion of the Yucatan arachnid arena was the tarantula, Brachypelma vagans.It wasn’t even close.

    While the Centruroides scorpions sometimes made the first attack, they were never successful. The tarantulas claimed all victories - catching and consuming their opponent about 60% of the time, no matter who they were facing. At last, Dor and her team were able to confirm their suspicions - predation by the tarantula keeps these two arachnids apart in the wild.
