Arguably one of the most variable Bembix species in terms of colour pattern … and therefore one of the most challenging to identify from field photos. Finally I have one in the hand and so can be more confident that this is indeed B. littoralis.

Last summer I captured images of Pseudoturneria territorialis females, both in the field and upon collection. But at that time no males were to be seen. More luck this year, as in early November males are suddenly swarming about the nesting site.

This is a relatively common species throughout coastal and near-coastal Queensland. Thanks to Scott W. Gavins, I take a closer look at key identification features of the female … including the clypeal lamina and the mesopleuron.
