Specimens of Neides spp. were only found occasionally at the adult stage. The larvae of A. pectoralis and M. annulosus are obviously capable of feeding on prey caught in the investigated spider webs. While A. pectoralis is also able to develop on plants, M. annulosus seems to be obligately associated with web-building spiders. Because of the stilt bugs' long, slender body and legs, the synapomorphic character of dentate claws within the Pentatomomorpha and the plesiotypic trophoecological behavior of the observed taxa, it is hypothesized that the ancestral berytid was living zoophagous as a commensal in spider webs.
