Nature of Aragon > Fauna

Within invetebrates, arthropods represent the group with articulated limbs, and within them insects are those with three pairs of joints and jaws.

The diversity of living beings increases the smaller their size. This rule, applicable to all invertebrates, reaches its highest degree in insects, of which it is estimated that there are no less than 1.5 million of species (75% of all animal species).
Faced with very different climates, soils and types of vegetation, the adaptation of a species to a certain environment can lead to astonishing specializations.
Suffice it to mention, for example, the 15 species of butterflies of the genus Erebia that live in the Pyrenees, each occupying a different biotope.

Such diversity, the result of natural selection, reaches its maximum in tropical regions and decreases as we approach the poles.
But the mountain ranges, such as the Pyrenees or the Iberian Cordillera, present in a few kilometers a variety of climates and types of vegetation that on the flat land would be thousands of kilometers apart. It is not surprising, therefore, that insects similar to those of the subpolar tundra live in the highest peaks of the Pyrenees, while in the sunny valleys we will find typically Mediterranean and African species.

Insects make up three-quarters of all animal species known so far (about a million and a half) and new ones continue to be discovered.


General characters of insects

They are arthropods, that is, with articulated appendages. They have six legs so they are also called hexapods.



The great diversity of insects makes it necessary to classification in orders of similar species.

The most colorful and well-known are the diurnal butterflies (Order Lepidoptera, suborder Ropalóceros).

A small presentation of the diversity of the insects could be the following:

Proturos They are the most primitive insects.
Without wings or antennae.
Colembolos Sin alas.
A ventral organ allows them to take great leaps.
Tisanuros Tres apendices terminales
Lepisma or silverfish
Dipluros Two terminal appendices.
Ephemeroptera Rudimentary mouthpieces.
Two pairs of wings.
Aquatic larvae with gills.
Plecoptera Incomplete metamorphosis
Odonates Chewing mouth.
Two pairs of large membranous wings.
Aquatic larvae.
Mantoids or mantids Incomplete metamorphosis
Mantis religiosa
Blactereos Mouthpiece masticator
Fasmideos Mouthpiece masticator
Insect stick
Dermapteros Mouth chewing.
Tongue at the end of the abdomen.
Orthotics Mouth chewing.
Two pairs of wings, of which the first protects the second.
Cricket, Lobster
Isopters Mouth chewing.
Social organization similar to that of ants.
Termes or Termites
Hemiptera Superorder that includes heteropteros and homopteros.
Heteropteros Mouthpieces choppers-suctors.
Two pairs of wings, the first one in its anterior part.
Homopteros Mouthpiece picador-suctor.
Two pairs of equal wings, which sometimes are missing.
Cicadas, aphids.
Hymenoptera Mouthpieces chewing or sucking.
Four membranous wings.
Bee, Wasp, Ant
MalophagosChewing mouthpieces.
Without wings.
Places of birds and mammals.
Lice of chickens.
AnoplurosMouth filler-suctora.
Without wings.
Mammals' parts.
Head louse.
NeuropterosChewing mouth.
Four membranous wings with numerous nerviations.
Lion ant.
ColeopteraChewing mouth pieces.
Two pairs of wings, the first very coro form a protective case.
Beetles, Fireflies.
Lepidoptera Mouthpieces transformed into suctor apparatus that is spirally wound.
Two pairs of membranous wings covered with scales.
Butterflies and moths.
Diptera Biting and sucking mouthpieces.
Just a pair of wings.
Fly, Mosquito, Tipula, Tabano

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.

Also you can dedicarte to the intangible ones: from the legend compilation that also does to universal Aragon.

The pasapues project is an extension of the Aragón project is like that, and tries to collect and relate all possible types of documentary information about Aragon: texts, books, articles, maps, illustrations, photographs, narrations, etc., and proceed to its publication and diffusion.
