It is a large order of insects with more than 25,000 species that are distributed throughout the world.
They are grouped, with the homopterans or cicadas, in the superorder of the Hemiptera.
They have a biting-sucking mouth apparatus that they use to feed on plant sap, blood or insects.
They have two pairs of wings: some chitinous, crossed over others membranous, folded. On their back they have a triangular gusset on whose sides the wings are attached.
Others have beetle-like shells, and many species, especially tropical ones, boast beautiful colors and even metallic luster. There are terrestrial and aquatic ones. The terrestrial ones give off a bad smell produced by excretory glands located in the back of the thorax.
Most heteropterans are harmful to agriculture and some feed on human blood and are disease transmitters.
Bed bugs pierce the skin of their victims by using two styluses that allow the sucking device to enter, with which they suck the juices and pump saliva downward.
Some field bugs:
Shoemakers glide over the water with their long legs.
Water bugs live on the surface and at the bottom of the water. There are several families of these insects, among which are the hydrometrids, which walk on the water, the notonectids, which swim with the belly up, the water scorpions, etc.
The water needle measures about 4 centimeters, it is very difficult to see it because it is confused with aquatic plants.
The backstroke swimmer (Notonecta) measures about 18mm, lives in rivers and lakes around the world. Swims on its back and attacks insects and minnows. They are very voracious.
The water scorpion (3 cm) has the front legs with very sharp nails to catch its victims, which are usually insects and minnows.
The barque bug (2 cm) lives in fresh and brackish waters around the world. It uses its legs as paddles.
The giant water bug reaches a length of more than 10 cm. They are predators of rivers and ponds, where they feed on insects, tadpoles and minnows.
All water bugs have a very painful bite.
A small presentation of the diversity of the insects could be the following:
|WITHOUT WINGS or Apteros|
|Proturos||They are the most primitive insects.|
Without wings or antennae.
A ventral organ allows them to take great leaps.
|Tisanuros||Tres apendices terminales|

|Dipluros||Two terminal appendices.|
Two pairs of wings.
Aquatic larvae with gills.
Two pairs of large membranous wings.
|Mantoids or mantids||Incomplete metamorphosis|
Tongue at the end of the abdomen.
Two pairs of wings, of which the first protects the second.
Social organization similar to that of ants.
Termes or Termites
|Hemiptera||Superorder that includes heteropteros and homopteros.|
Two pairs of wings, the first one in its anterior part.
Two pairs of equal wings, which sometimes are missing.

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.
A small list of species in Aragon would be the following:

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.
