What they are - biological definition

Diptera are insects that belong to the Diptera group. The word originates from the Greek, and di means two and ptero means wing. Therefore, the main feature that differentiates insects from this group from others is the presence of two wings.

There are about one million species of dipterous insects, but only 155,000 are known and cataloged (described) so far. They are present in almost every region of the world. They are rare only in extremely cold climate areas such as the Antarctic and Arctic region.

Summary of main features:

- Existence of two developed wings.

- Like all other insects, the body of the Diptera is divided into head, thorax and abdomen.

- They have radical metamorphosis, meaning the body changes a lot from birth to adulthood.

- The life cycle has four phases: egg, larva, pupa and adult phase.

Taxonomy

The order Diptera is divided into two suborders: Brachycera (have antennas with presence of 3, 4 or 5 segments) and Nematocera (dipterans with antennas with more than six articulated free-form segments).

Examples of dipterous insects:

- House Fly

- Flower Flies

- Straw mosquito

- Blowfly

- Bathroom Fly

- Aedes Aegypti

- nail mosquito (Anopheles)

- Common hawk (Culex pipiens)

Biological Curiosities:

- Some insects do not have wings such as fleas, lice, termites, ants and book moths.

- According to scientists, we have information on the existence of dipterous insects since 240 million years ago (Middle Triassic).
