ABSTRACT:
We present informations about prey spontaneously captured by species of Loxosceles that inhabit caves in Brazil. These events were registered during visits by systematic collection of invertebrates in caves in the Caatinga, Cerrado (Brazilian Savannah) and Atlantic Rain Forest biomes from 1999 to 2011. Twenty four predation events were registered in more than 500 visited caves. All the observed prey include arthropods. Insects correspond to 73% of the prey, the remaining being Pseudoscorpiones, Araneae and Diplopoda. Diptera was the most representative order, with 28% of occurrence. The generalist habits and cannibalism observed in Loxosceles spp., is probably due to the food resource shortage conditions inside the caves that can result in low prey availability
