These species bear a variety of names, including Australian native honey bees, native bees, sugar-bag bees, and sweat bees (because they land on people's skin to collect sweat).

Monodontomerus can be a serious pest of O. lignaria, but Leucospis is less common and Melittobia is more likely to parasitize other later emerging Osmia. Several species of cuckoo wasps, relatively large and metallic green, also consume Osmia larva, but these wasps develop next to the juvenile bee and consumes the larva from the outside. [4]
