Resumen

Reportamos las dos principales presas autóctonas de la araña introducida Parasteatoda tepidariorum (C.L. Koch, 1841) en dos hábitats antropogénicos de los Alpes italianos, específicamente una especie de lagartija y una especie de escorpión: Podarcis siculus (Rafinesque, 1810) y Alpiscorpius sigma Kovařík, Štundlová, Fet & Šťáhlavský, 2019. Además, describimos brevemente el comportamiento depredador de esta araña con ambas presas, destacamos la escasez de registros de depredación de invertebrados sobre vertebrados en Europa y comentamos posibles efectos negativos sobre las poblaciones autóctonas.
