More Details

Taxonomic complexity

The contains over 400 described and is taxonomically challenging. Recent revisions employ integrative combining morphological characters (especially male ) with mitochondrial COI barcoding. Several species groups or subgenera have been proposed, including Metadorylas, though remains under study.

Research gaps

Most ecological and behavioral information for Eudorylas derives from studies of a few economically relevant . The vast majority of species have no documented associations or data.
