Wasps, although less recognized as good pollinators, also feed on nectar and pollinate flowers. Specialized pollination systems, such as orchids that mimic the pheromones of female wasps to attract males, are complex and specific. This interaction occurs with some Thyninnae wasps that also visit flowers to obtain nectar and perform other ecosystem functions. Therefore, the objectives of this study were: Survey literature on interactions between these wasps and flowers globally; Assess patterns of flower visitation using interaction network metrics; Enhance records of interactions by analyzing pollen on the bodies of species from the Neotropical region. To achieve this, we conducted a comprehensive search in online databases such as Web of Science and Google Scholar to study Thynninae and plants, and reviewed images on platforms like Flickr and iNaturalist. Interaction networks between plants and wasps were constructed, where we evaluated modularity, the role, and the degree of species. We analyzed pollen on 16 Thynninae species from different biomes in Brazil and Colombia, identifying pollen grains and assessing the diversity of plants visited. We recorded 359 interactions between Thynninae and plants, with 130 for nectar, 228 through sexual deception, and one associated with feeding behavior. We found 41 genera of wasps interacting with 41 genera of plants. The most frequent nectar-seeking interactions between Thynninae wasps and flowers were with Eucalyptus (20) and Leptospermum (19). The interaction network presented species with low degree, meaning few interaction records per species, and a modular network structure. Pollen analyses revealed that Pseudoscotaena aff. polistoides uses Achyrocline albicans as an important food source. The study highlights the importance of Myrtaceae as a significant nectar source for these wasps. We documented the first records of Thynninae in the Neotropical America and suggest future studies on their behavior and pollination efficiency.
