Resumen:
Predation is one of the main causes of mortality in natural amphibian populations and may occur in any stage of the life cycle. Many authors have pointed out that arachnids (mainly Aranae) are one of the most important predators of tadpoles in the Neotropics. Most of these records belong to Pisauridae, Ctenidae, Lycosidae, Sparassidae, and Theraphosidae families. However, predation on adult and juvenile amphibians has been poorly documented, mainly due to the difficulty of obtaining direct records in the fieldHere we present the first records of two species of lycosid spiders preying on H. pulchellus. Given that spiders of the Lycosidae are abundant in the Argentine Pampas grasslands, they could have an important role in regulating H. pulchellus populations.
