They are medium or large sized insects, elongated body and two pairs of very delicate membranous wings.
They have short antennae, highly developed compound eyes and chewing mouthpiece.
dragon-fly. Odonatos. Insects
They are very voracious carnivorous predators and hunt their victims on the fly.
They are excellent flyers able to stand still in the air and fly backwards.
Typical representatives of this order are dragonflies and Damselflies.
Dragonflies rest with wings extended.
Wingspan dragonfly: 11 cm.
Damselfly Wingspan: 5 cm.
The damselflies rest with wings folded back.
Metamorphosis
The metamorphosis of odonates is incomplete.
Through different molting phases, the larva becomes a nymph and it becomes an adult imago or insect.
The female lays eggs in water or in aquatic plants.
Larvae are aquatic and breathe through tracheobranchs.
They have a modified mouthpiece with a large lower lip in the form of a "mask" extensible towards their prey.
The nymph lives in its aquatic phase for a year or more. While growing, shed skin several times.
Before the last molt, it goes out of the water through the stem of a plant.
The skin cracks in the back and an adult comes out who, when the skin and wings harden, fly and complete the reproductive cycle with mating between males and females.
A small presentation of the diversity of the insects could be the following:

The SEA is realizing a complete Catalog of the Aragonese Entomofauna that has already been partially published, where 190 families have been inventoried with 3012 species.

Also Aragon enjoys a diverse and varied Nature where passing by plants, animals, Geology, or landscapes we can arrive at a fantastic bestiary that lives in its monuments.
The information will not be complete without a stroll by its three provinces, with shutdown in some of its spectacular landscapes like Ordesa, the Moncayo, Monegros or by opposition the Ebro.
