I regularly see these guys in my garden but this is the first time I've managed to photograph one. Google tells me that it's a Tyde's Sand Wasp (podalonia tydei) . It seems to be quite common, but I haven't been able to find any information about it.
My first thought was wasp… but I’ve not seen this particular one before. Nice focus on the head and legs… I like the way the wings are soft and have some nice bokeh.
