Hymenoptera - Wasps

The following table lists the species in this taxon assessed under the Singapore Red List, which is also published in the third edition of the Singapore Red Data Book.

You may find information for the conservation statuses assessed in the second edition Singapore Red Data Book (RDB2) and third edition Singapore Red Data Book (RDB3).

The information below is accurate as at the time of the listing online for the taxon.

This checklist provides comprehensive coverage of groups such as Vespinae and Sphecidae, but others such as Eumeninae, Scoliinae, and Crabronidae require further attention. Several taxa are treated as morphospecies and are potentially undescribed. Besides listing a few threatened taxa, we designate some wasps that are commonly recorded across land use types as Least Concern. Additional species assessments are planned for the future.
