Although bees are not my main focus, I have taken the opportunity to take a closer look at some of those turning up in the Malaise traps this year (as part of our participation in the International Barcode of Life project).
The Malaise trap survey we began 4 months ago is uncovering the diversity of our smallest wasps … including Rhopalum. They vary in colour, size, and most notably, in the shape of the gaster.
