Dragonflies
(suborder Anisoptera, order Odonata, infraclass
Palaeoptera, subclass Pterygota, class Insecta, subphylum Hexapoda, phylum
Arthropoda)
Dragonflies are predators that chew their food, have four
wings that cannot be folded and undergo incomplete metamorphosis. They have
a distinct young adult stage ("teneral"), looking like females for some time after last molt
and completion of wing development, after which the males make a gradual transition
to their distinctive colors. They are rapid and agile fliers that can
control their forewings and hind wings independently; they can mate in flight.
Nymphs are aquatic and adults terrestrial, although they rarely stray far from
water. Sometimes they land in the water by mistake, perhaps when they are
old or sick, and cannot escape. Methods of capturing prey vary: Blue
Dashers, at one extreme, maintain a perch and wait for prey to come by;
Wandering Gliders, on the other hand, are almost constantly flying at high
speeds.
Dragonflies evolve bigger bodies when exposed to heat

Dragonfly Exuviae
These used to be exoskeletons of dragonfly nymphs, which
exited through dorsal slits in the thorax. We usually don't get to see them in
action because they emerge at night.

Darners
(Family Aeshnidae)
Darners are large dragonflies, up to five inches long. They are not
especially common, but are very conspicuous when flying.

Clubtails
(Family Gomphidae)
Like the Darners, Clubtails are large and conspicuous.
Their distinctive eyes are widely separated. When at rest, they tilt their
abdomens upward slightly. The "club" on their tails is not as striking as
one would expect from their group name.

Skimmers
(Family Libellulidae)
Skimmers are the most common family of dragonflies.
Their otherwise round eyes appear to be at least slightly flattened against each
other (commonly described as "connected"). Unlike Darners and Clubtails,
their abdomens are relatively short relative to the length of their wings.
