Phylogenetics and Taxonomy of Social Wasps

The family Vespidae encompasses a diverse array of social wasps, spanning temperate paper wasps (Polistinae) to tropical swarm-founders (Epiponini) and hornets (Vespinae). Early taxonomic schemes relied on morphological characters such as wing venation, nest architecture and genitalia to delimit subfamilies and genera. In recent decades, molecular markers—including mitochondrial genes, nuclear loci and complete mitogenomes—have been incorporated to reconstruct robust phylogenies. These integrative analyses consistently support the monophyly of major lineages and a single origin of eusociality, while also revealing paraphyly in several genera, driving taxonomic revisions and the description of cryptic species. DNA barcoding protocols and non-destructive genetic sampling of museum specimens have further enabled the inclusion of rare or extinct taxa, enhancing taxonomic resolution. A refined classification not only clarifies evolutionary relationships but also underpins studies of social behaviour, pest control and ecosystem services. Continued fusion of morphological, molecular and behavioural data promises to resolve deep divergences and microevolutionary processes within this globally significant group.

Phylogenetics and Taxonomy of Social Wasps publication trend

The graph below shows the total number of articles in phylogenetics and taxonomy of social wasps across all publications each year (not limited to Nature Index journals).

Technical terms

Monophyly: A group comprising a common ancestor and all its descendants.

Paraphyly: A group that includes a common ancestor and some, but not all, of its descendants.

Mitogenome: The complete mitochondrial genome, often used as a molecular marker in phylogenetic studies.

DNA barcoding: The use of a short, standardized genetic sequence to identify species.

Integrative taxonomy: An approach combining morphological, molecular and ecological data to delimit and describe species.

Eusociality: The highest level of social organisation, characterised by cooperative brood care, division of labour and overlapping generations.
