Veronica chamaedrys (Plantaginaceae) is a good example to review the difficulties that arise with the study of the relationships between entomophilous plants and insect anthophiles, both from the standpoint of acquisition techniques and literature analysis. This widespread species has been studied by pollination biologists since as early as the 1870s. There are, however, only a few detailed original works that provide insight into the main pollinators of this species, such as bees Anthophila (Apoidea, Hymenoptera) or hoverflies (Syrphidae, Diptera). Most other papers on the topic either ultimately contain just references to these (often through the mediation of others, thereby losing information about the employed methods and validity of the conclusions) or the insect visitor lists, which vary greatly from paper to paper and are sometimes limited to one family, order, or other group. We studied the quantitative composition and behavior of insects on the flowers of V. chamaedrys at the Zvenigorod Biostation of the Moscow State University (Odintsovo district, Moscow oblast) during the bloom seasons of 2014–2016. Large beetles from the Oedemeridae and Malachiidae families, in addition to bees and hoverflies, proved to be possible pollinators. Also, according to our data, the rather limited V. chamaedrys consortium includes several groups of the nectar and pollen thieves (representatives of several families of small Diptera, Lepidoptera, and Coleoptera), which account for the majority of visits. This fact was occasionally mentioned but was hardly ever analyzed in detail in previous studies, possibly because insects that do not participate in pollination were of little interest to the researchers. These “illegitimate” visitors, however, must be taken into account for a full understanding of the plant–insect coevolution and the functioning of consortia.
