he van der Vecht and Richards’ glands, found only in certain eusocial wasps in the Vespinae and Polistinae subfamilies, are located on the underside of the abdomen.

The black rectangle indicates the approximate area shown in microscope view (B), where dotted ovals indicate the gland locations. (S5 and S6 indicate metasomal sternites 5 and 6.)
