Resumo

The jumping spiders Enstiromastix nativo, Psecas sumptuosus, and Uspachus sp. n. (Salticidae) live on terrestrial bromeliads in areas with different phytophysiognomies in southeastern and northeastern Brazil. To understand these spider-plant interactions, we investigated if (1) these spiders were associated specifically with bromeliads, (2) the spiders utilized particular bromeliad species, and (3) plant size and density of bromeliads affected spider distribution. The jumping spiders were not found outside bromeliads, indicating a strict spider-plant association. Eustiromastix and Uspachus occupied bromeliads in open areas, whereas Psecas was found on forest bromeliads. Eustiromastix occurred at a higher frequency on larger bromeliads and in patches with higher bromeliad density This is one of the few studies to demonstrate specific relationships between jumping spiders and a particular plant type.
