Order-level prey compositions for four sympatric Tetragnatha species from the Hawaiian island of Maui, as recovered by molecular gut content analysis based on a short COI amplicon. The different lifestyles of the web builders (T. acuta and T. stelarobusta) and free-hunting species (T. quasimodo and T. waikamoi) are reflected in divergent prey spectra. However, prey community differences also become apparent within web builders and free hunters. This effect may be due to interspecific differences in microhabitat and prey capture strategy. The green T. waimamoi resides and hunts on green leaves, while the brown T. quasimodo occurs on tree bark or dead leaves. The two web builders are distinguished by different web mesh widths, selectively catching different arthropod groups. Based on data from Kennedy et al. 2019
