I really should go buy a macro lens — these close-ups of heads and eyes are intriguing. Those are not white dots on top of the eyes, but light reflections off the cluster of ommatidia (see post on June 22 for diagram of dragonfly eyes). You can almost see the individual ommatidia in the reflection of the meadowhawk below. Click on any image to get a higher resolution view.
The head of a male Widow Skimmer. Purple-ish eyes and blue mouth parts.
Head of a female Ruby- or White-faced Meadowhawk (the male has the white face). It almost seems that the eyes are bi-colored, as they reflect different wavelengths of light from their top and bottom.
Some kind of hairy fly with a white face and big red eyes. What does it do with all those long hairs on its back?
Nymph of the very common Differential Grasshopper (about 1/2 inch long). Very strange eyes on this critter. What a difference in the size of the eyes of this herbivore vs the predatory dragonflies.
I think I am going to need more camera equipment…these photos were all taken with the Canon 100-400 telephoto lens, which just doesn’t get me close enough on the tiny critters.
