Bug hunters love flowers, not just for their own sake but for the bugs they attract. This set of photos shows most of the insects I saw in just ten or fifteen minutes on one profusely flowering shrub in Anderson Park, beginning with the wasps.
This wasp is possibly a Blue Flower Wasp, Scolia soror, and certainly a close relation if not that particular species. There was another similar one feeding on the same shrub, distinguishable by a bright yellow patch on the back of its head; it may have been Scolia verticalis (see them both here, on Graeme Cocks’ site).
Scoliidae is just one family of wasps, the Flower wasps. Gasteruptidae (top pic) is another (BugGuide calls them “Carrot Wasps” and you can see why, but I don’t think they have a genuinely common name), and there are many more including Polistinae, the Paper wasps. This index page on Graeme’s site shows them with their nearest relations, the bees and ants.
This small native bee (Colletidae) is similar to one which appeared on my earlier all-on-one-plant post. The beetle below is not just similar – it is definitely the same species:
The odd angle of this shot was forced on me by my uncooperative subject but does allow me to point out a neat bit of mimicry: the eye-spots and tails on the lower part of the wings are a surprisingly good imitation of the butterfly’s head and antennae (there’s an even more striking example here, on a related butterfly). I’m sure this is not a coincidence, since tricking predators into attacking non-vital parts is great for survival.
All the other insects here were attracted to the flowers. This dragonfly just wanted to perch for a while and found a suitable bare twig. He happens to be the first carnivore (insectivore?) on the page and he may well be looking out for prey amongst the smaller bugs attracted to the flowers. As I said in the beginning, bug hunters love flowers.
