36 M. Suvák nities to encounter such diaspores. Sanders (2013) assumed greater potential for interactions between plants and spiders, especially based on the wide range of spider families using nectar as supplementary resource. Another very widespread potential plant resource – diaspores with elaiosomes, in con- nection with preliminary observations described in this paper, show that herbivory in spiders may be more common than previously assumed. Acknowledgements I would like to thank the reviewers Martin Nyffeler and Rainer Foelix for their valuable comments on the earlier version of the manuscript, although any possible remaining errors are my own.
