Improving and reconstructing data about the network between Orthoptera and flowers in Southeast Asia

Flower visitation by orthopterans, particularly by taxa from Southeast Asia, was only recently brought to light in a report on the diversity and network of 41 orthopteran taxa from Southeast Asia visiting flowers of 35 plant taxa. Continued efforts to document flower visitation by orthopterans have led to 104 new incidences of flower visitation by orthopterans, including 17 new orthopteran taxa. A total of 247 incidences of 58 flower-visiting orthopteran taxa visiting 71 genera of flowers are reported here. In accordance with previous studies, the subfamily Phaneropterinae remains the most prominent flower-visiting orthopterans reported in Southeast Asia and is very likely undisputedly floriphilic. Using a dataset from previous years, the phylogenetic signals of flower-visiting orthopterans and the floral traits of the plant taxa visited are also discussed. However, we recommend caution against drawing too much inference at present owing to the unresolved phylogenetic relationships between the taxa involved and the incompleteness of the current dataset. Therefore, this paper primarily offers an updated list of flower-visiting orthopteran taxa and the flowers they visited. For a more comprehensive understanding of the flower-visiting orthopterans in the region and their ecological impacts, continued natural history research is needed.
