Anyone knows about some damselflies?

Question

What does a damselfly eat?
And what does it do during the day or night?

Please help....>.<"

Answer 1

Damsel flies feed on other insects, as do their relatives the dragonflies. They fly during the day and sleep at night. Some species do fly in dark areas of forests only, though still during the day. Odanates (dragonflies and damselflies) are really cool bugs. They can display amazing colors. They can be amazingly fierce hunters, taking insects larger than themselves.

Answer 2

Damselfly

The Damselfly (Suborder Zygoptera) is an insect in the Order Odonata. Damselflies are similar to dragonflies, but the adults can be differentiated by the fact that the wings of most damselflies are held along the body when at rest. Furthermore, the hindwing of the damselfly is essentially similar to the forewing, while the hindwing of the dragonfly broadens near the base, caudal to the connecting point at the body. Damselflies are also usually smaller, and weaker fliers than dragonflies, and their eyes are separated.

Biology

Damselflies undergo incomplete metamorphosis, with an aquatic nympal stage. The female lays eggs in water, sometimes in underwater vegetation, or high in trees in bromeliads and other water-filled cavities. Nymphs are carnivorous, feeding on daphnia, mosquito larvae, and various other small aquatic organisms. The gills of damselfly nymphs are large and external, resembling three fins at the end of the abdomen. After molting several times, the winged adult emerges and eats flies, mosquitoes, and other small insects. Some of the larger tropical species are known to feed on spiders, hovering near the web and simply plucking the spider from its perch there.
