Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
They squirt water out from the ends of their abdomens. They will generally take several years to mature, and when the immature changes into a dragonfly, it does so at night. This behavior probably was evolved to avoid being eaten be daytime predators. The adult generally flies from late April to November, and does all of its hunting while on ...
Dragonflies having simple flaps shed the eggs in water, mostly in flight. Dragonflies having ovipositors use them to puncture soft tissues of plants and place the eggs singly in each puncture they make. [32] [34] [35] [36] Dragonfly nymphs vary in form with species, and are loosely classed into claspers, sprawlers, hiders, and burrowers. [17]
An immature flame skimmer feeds mainly on aquatic insects. Its diet consists of mosquito larvae, aquatic fly larvae, mayfly larvae, freshwater shrimp , small fish, and tadpoles. The nymphs, which live in the mud at the bottom of warm streams or ponds, catch their prey by waiting patiently for it to pass by.

Before reproduction can occur, a male must first establish a territory. These territories range from 2–4 metres (6.6–13.1 ft) in area and sit close to bodies of water. Male dragonflies patrol these areas and defend them from dragonflies of both their own and other species. Females initiate mating by flying into a male's territory.

The naiads live in the debris of the bottoms of lakes and ponds. They do not actively pursue prey but wait for it to pass by, a strategy which affords them protection from other predators. The naiads emerge from the water to make the transition to adult dragonflies at night. Adults fly from early August through October.
