is a Dragonfly?
Dragonflies are in the Odonata order (including
damselflies) and are a primitive species of flying
insects that can hover mid-air. They evolved during
the Mississippian Period 360-325 million years
ago. Dragonflies are characterized by a pair of
large compound eyes, their elongated abdomen and
two pairs of often transparent membranous wings.
Their aquatic nymphs are voracious and water jet-propelled.
Currently about 5000 species of dragonflies and
damselflies are known; experts guess that there
are probably only between 5500 and 6500 species
What do Dragonflies Eat?
dragonflies eat mostly other flying insects, particularly
midges and mosquitoes. They will also take a piece
of butterflies, moths and smaller dragonflies.
Dragonfly larvae, which live in water, will eat
almost any living thing that is smaller than them.
Large dragonfly larvae sometimes eat small fish
or fry in the water, but usually they only eat
bloodworms or other aquatic insect larvae. Dragonflies
are found in nearly all parts of the world and
you can now start your own dragonfly collection
with a framed dragonfly and our life-like electronic
moving dragonflies. If you are looking to have
artificial dragonflies in your home or office
electronic moving dragonflies are very realistic
and can even fool an entomologist at first!
can I Tell a Dragonfly from a Damselfly?
Damselflies are usually slim, their forewings
and hind wings narrow at the base and have similar
shapes, and their eyes are widely separated. Most
species hold their wings above their abdomen when
they are resting. On the other hand, dragonflies
are much larger with eyes that touch near the
top of their heads. Dragonfly wings do not narrow
at the base; and their forewings and hind wings
differ in shape. When resting, their wings are
usually wide spread.
How Long do Dragonflies Live?
Most temperate-zone species of dragonflies live
as adults for less than a month, with some species
living as long as six months.
What Enemies do Dragonflies and Damselflies
natural enemies are birds, spiders, frogs, and
larger dragonflies. In the larval stage, they
are preyed upon by fish, frogs, toads, newts,
and other water invertebrates.
How Many Lenses are in a Dragonfly's Eyes?
Dragonflies have as many as 30,000 lenses in each
What is the Biggest Dragonfly and Damselfly?
The Megaloprepus coerulatus damselfly of Central
America is the biggest living dragonfly with a
wingspan of 7.5 inches. The bulkiest known dragonfly
is the Petalura ingentissima from Australia with
a wingspan up to 6.5 inches. The largest dragonfly
in the fossil record had a wingspan of 29.5 inches.
What is the Smallest Dragonfly?
Several dragonflies in the genus Agriocnemis have
a wingspan of just 7/10ths of an inch.
What is a Nymph?
nymph is an immature form of the following insect
species: locusts, cicadas, mayflies, termites,
crickets, grasshoppers, cockroaches, mantids,
and dragonflies. In this stage of development
it has undergone incomplete metamorphosis. It
should not be confused with a larva, as its overall
form is already that of an adult.
