Xenoglossa strenua. People who know something about native bees often know about the "Squash Bee" Peponapis pruinosa. However, there are other native squash bees, and here is one. This is Xenoglossa strenua.

One of the most common bees in the East...if only we could figure out how to identify it more easily. Here we have Lasioglossum trigeminum. Fits right in with A. admirandum, A. versatum, and A. callidum and I often struggle with dark second thoughts about the specimens Id, because of all the overlap.

A common Carpenter Bee in Kruger National Park where they hang out in blooming trees (particularly legumes) once the trees start blooming with the austral spring rains. Looks a bit like the road stripers got a hold of her. Xylcopa caffra. Identified by Jonathan Mawdsley. Photo by Kelly Graninger.

Another bee from Kruger National Park in South Africa. This is Xylocopa caffra...the male. Note how it is all yellow? Well the female is almost all black with some blocks of yellow on the abdomen. In a number of Carpenter bees on a number of continents this pattern repeats...while in other Carpenter bees the male and female are both dark.
