Chalcidoid wasps now have an excellent database all their own thanks to John Noyes of London's Natural History Museum. The Universal Chalcidoidea Database contains an extensive set of taxonomic and bibliographic records, as well as nearly 400 photos of living chalcidoids. Users will also find a key to chalcidoid families, information on collecting and preserving specimens, and a brief overview of this extremely diverse yet poorly understood group of wee wasps, which includes the world's smallest adult insect -- measuring in at a mere 0.11 mm.
