Citrus flatid planthopper (Metcalfa pruinosa)
A fairly large planthopper, found on the branch of a black locust tree.
European paper wasp (Polistes dominula)
These are the wasps that build the small open-bottomed paper nests affixed to eavestroughs, or in bird boxes, etc. They are not a very aggressive wasp and I have no problems photographing their nests and getting quite close. They will react if they fear danger, but then who wouldn't!
Obedient plant (Physostegia virginiana)
A beautiful native plant (native a bit further south than here, though it does very well in this region) that attracts numerous insects.
Bottle gentian (Gentiana andrewsii)
Growing in profusion in the Butterfly Meadow. These odd flowers do not open, but they are pollinated. I have seen bumble bees work their way in, and one site I checked notes that bumble bees may the only insect tough enough to push their way into these flowers and in the process help pollinate them.
Red squirrel
This little red kept up a steady and loud chittering for the 10 minutes or so I was in his vicinity. They always sound like they are having a major hissy fit!
Sneezeweed (Helenium autumnale) and obedient plant (Physostegia virginiana)
The combination of these two native flowers is especially pleasing to the human aesthetic and is also pleasing to many bees and wasps and other insects who visit these plants for nectar.
