The previous posting caught up on miscellaneous recent pictures of birds; this one does the same for bugs—bugs being used as a rather informal term for any arthropod.
Bluets copulate in the wheel position; the male is bluish, the female brownish. The arrangement among these damselflies is similar to that used by dragonflies, but the male holds the female by the neck rather than the back of the head and the female’s legs grasp her own abdomen, not his. Compare this image to those of copulating dragonflies presented in Sex in the park and Grohman extras.
This dragonfly is a darner—probably a Shadow Darner. Darners don’t hunt from a perch, but hunt on the wing. Focussing on a small rapidly moving object is tricky. Unlike most insects (such as bees) the four wings do not move up and down in unison. When the rear wings are up, the front wings are down, and vice versa.
This dragonfly is a Cherry–faced Meadowhawk. Compare this with the picture of the White–faced Meadowhawk shown at Grohman extras.
Finally, here is a butterfly: a Western White. The Western White does best in warm dry conditions, just what we had through August and early September.
