I spotted a very large, 3 to 4 inch dragonfly up in Northern California flying by my window one night around 10:00 P.M. It was flying slowly though - the temperature outside was about 50 degrees in mid July. Elevation was about 5,000 feet.
In full darkness, no. Their large compound eyes are made up of many small lenses and light-sensitive cells, which gives them very good vision in almost all directions. They also have ocelli, which are "simple eyes" capable of sensing light, but not determining its direction. Most dragonflies are active during the day and perch when light begins to fade. Some species are active when light is poor at dawn and dusk, but not in full darkness.
Dragonflies actually soar around constantly. They are carnivores, eating bees, ants, and other insects.
Dragonflies roost at night and have a nest that they go to. This is where they rest. A dragonflies metabolism slows down in the evening causing them to rest. This effect is known as torpor.
They don't. :P You must've seen them in a weird light, or they weren't dragonflies. Only fireflies have bioluminescence.
Smashing other dragonflies. And I mean hard!
They perch and wait for daylight.

No. Dragonflies loose the ability to go underwater.
No. Water dragons are diurnal, meaning that they are only active during the day.
they go to ponds
No. Dragonflies only go after live prey.
Dragonflies go on top of each other and fly because sometimes they are husband and wife staying together.
