Blüthgen (1938: 279) listed this species as a synonym of Euodynerus (Pseudepipona) lativentris but with a question, while van der Vecht & Fischer (1972: 83) treated P. beckeri as a separate species, with O. falsus as its questionable synonym. Ethology. Imagines of this species were previously recorded at flowers of Eryngium campestre L., Ferula caspica M. Bieb. (both Apiaceae), Tripolium pannonicum (Jacq.) Dobrocz. (Asteraceae), Butomus umbellatus L. (Butomaceae), and Limonium scoparium (Pall. ex Willd.) Stank. (Plumbaginaceae) (Fateryga 2020).According to the label data, specimens of P. beckeri were also collected at Matricaria sp. (Asteraceae), Euphorbia sp. (Euphorbiaceae), and Medicago sp. (Fabaceae). Further field observations of this species in Crimea revealed feeding of imagines on Anthemis ruthenica M. Bieb. (Asteraceae) (Fig. 2B), Lepidium crassifolium Waldst. & Kit. (Brassicaceae), and Galium humifusum M. Bieb. (Rubiaceae). Pseudepipona beckeri was also recorded licking buds of Verbascum phlomoides L. (Scrophulariaceae), together with Brachyodynerus magnificus (Morawitz, 1867) (Fateryga et al. 2017; Fateryga 2020). Fateryga (2020) previously suggested that these wasps might consume liquid exuding from the minute pores in the plant epidermis. Present observations, however, revealed that buds of V. phlomoides visited by P. beckeri had numerous perforatrions made by a true bug species (Hemiptera: Heteroptera) (Fig. 2A). Therefore, use of these perforations to uptake plant sap by the wasps can be speculated.
