Mocha Emerald dragonflies spotted in flight at the "Wildlife Sanctuary." The flight period for adult Mocha Emerald dragonflies seems to be approximately one month for this location, centered on mid-July. Mature Mocha Emerald dragonflies have emerald green eyes, as their name suggests -- don't be fooled by the play of light off the 30,000 facets in each of the dragonfly's compound eyes! Speaking of the play of light, the "bokeh" in the background is caused by out-of-focus points of light reflected from the surface of the water about one- to two feet below the dragonflies.
