Even though scorpions are fierce predators, they also have their own enemies. According to Gary Polis' "The Biology of Scorpions" around 150 taxa have been listed as predators on scorpions. Most of them were vertebrates, but also invertebrates have scorpions on the menu (including scorpions eating scorpions). In a recent research note, Zamani and Rossi reported of a case of intraguild predation where the spider Parasteatoda tepidariorium (C. L. Koch, 1841) caught a male Euscorpius concinnus (C. L. Koch, 1837). The note also discuss other examples of spider predation on scorpions.
Abstract:
We report a case of intraguild predation by the spider Parasteatoda tepidariorum (Theridiidae) on the scorpion Euscorpius concinnus (Euscorpiidae) from Tuscany, Italy. The most interesting aspect is the impressive difference in size between the predator and the prey.
