The prey animals include various beetles and their larvae, caterpillars, cicadas and spiders as well as representatives of the related phytophagous stink bugs of the subfamily Pentatominae . For this reason, the bug species is considered a beneficial insect . The nymphs show a gregarious behavior . They attack several larger prey animals.
