Argentine ant infestation affects the abundance of the native myrmecophagic jumping spider Siler cupreus Simon in Japan

Research article

Abstract.

The effect of an Argentine ant invasion on the abundance of the myrmecophagic jumping spider Siler cupreus Simon was investigated in the Hiroshima Prefecture, southwestern Japan. The frequency and density of S. cupreus were significantly higher in sites infested with Argentine ants than in ant-free sites. S. cupreus actually preyed on the adult ants and the brood. The dominance of Argentine ants possibly provides an abundant food source for S. cupreus, thus causing an increase in the number of spiders.
