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.

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.

Of all the pictures I took up at Laurence's this is by far my favorite. I love the geometry, the complementary colors, the contrast between the texture of the abdomen and the texture of the wing, and just the lushness of the whole thing. Here we have a Xylocopa from Kyrgyzstan to thank.

100 years old and still blue .... ish. Google Xylocopa caerulea to see some knockout recent specimens. Capture in Singapore long ago. Interesting to think what legacy you will have in a 100 years...? Will people still use and find relevant something you did/found/created 100 years from now? Picture taken by Anders Croft.
