Pentazeleboria Thynnid Wasp - a photo on Flickriver

Pentazeleboria Thynnid Wasp

            Pentazeleboria janeta Brown 1983
Subfamily: Thyniinae
Family: Thynnidae
Order: Hymenoptera

This species was was first noticed in 1910. Four more specimens were found over the next 70 years and it was finally named as a species in 1983 - Pentazeleboria janeta - by Dr Graham Brown. As far as I can see, it hasn't been photographed in the wild before; there appear to be no photographs of live wasps on iNaturalist/ALA or other databases.

The wasp in the photo is a male. Thynnid females are wingless and burrow in the ground.

The male Thynnid wasps collect nectar and stash it under on metasomal hairs to present as a copulatory gift to females. This photograph appears to show nectar being stored in the hairs on the end of the metasoma.

The series of photos in the comments below are of several individuals of this species that were photographed in the same area of the reserve on three separate days over a week in early October 2022. (Click on photo for more details of the observation).
