The Protanisoptera, another ancestral group that lacks certain wing-vein characters found in modern Odonata, lived from the Early to Late Permian age until the end Permian event, and are known from fossil wings from current-day United States, Russia, and Australia, suggesting they might have been cosmopolitan in distribution.

Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight. They have large eyes that take up nearly the entire head surface and when not contiguous are not as widely separated as within the damselflies (see the key below). The obelisk position orients the dragonfly's abdomen directly at the sun, thereby reducing the surface area exposed to solar heating. Some defend a territory against others of their own species, some against other species of dragonfly and a few against insects in unrelated groups. Mating takes just a few seconds, after which the female can immediately lay her eggs. The male attempts to prevent rivals from removing his sperm and inserting their own,[53] something made possible by delayed fertilisation[39][51] and driven by sexual selection.

Most species need moderate conditions, not too eutrophic, not too acidic;[41] a few species such as Sympetrum danae (black darter) and Libellula quadrimaculata (four-spotted chaser) prefer acidic waters such as peat bogs,[42] while others such as Libellula fulva (scarce chaser) need slow-moving, eutrophic waters with reeds or similar waterside plants. 1 ) Dragonflies were some of the first winged insects to evolve, some 300 million years ago.

And while they share some physical characteristics, there are four ways you can differentiate between the two, according to Mother Nature Network . . [62], Dragonflies generate lift in at least four ways at different times, including classical lift like an aircraft wing; supercritical lift with the wing above the critical angle, generating high lift and using very short strokes to avoid stalling; and creating and shedding vortices. Notes: Unlike most other dragonfly larvae, which sit and wait for prey, aeshnid larvae stalk their prey. "[112], The novelist H. E. Bates described the rapid, agile flight of dragonflies in his 1937 nonfiction book[113] Down the River:[114], I saw, once, an endless procession, just over an area of water-lilies, of small sapphire dragonflies, a continuous play of blue gauze over the snowy flowers above the sun-glassy water.

They hunt in flight, are highly manoeuvrable and even mate mid-air. Is a dragonfly an insect or a bug? Larvae absorb oxygen from the water using gills inside the rectum. Blues are typically created by microstructures in the cuticle that reflect blue light. Eventually, the larva crawls out of the water (often at night) and molts one last time, emerging as an adult and leaving behind a cast skin (exuvia).
