UNIRAMIA/INSECTA
In the subphylum Uniramia, insects form a class that includes grasshoppers, roaches, ants, bees, butterflies, flies, and beetles.

With more than one million insects identified, insects are considered to be the most successful group of animals on our planet in terms of diversity, geographic distribution, and number of species.

Most insects live on land, though others inhabit fresh and marine environments.

Grasshoppers share the typical body design found on all insects:

• Three body parts (head, thorax, and abdomen)
• A single pair of antennae attached to the head
• Three pairs of legs attached to the thorax

Insects breathe by exchanging gases through a series of air sacs and tubular channels collectively called tracheae (the singular form is "trachea"). Oxygen entering these passages goes through spiracles, tiny openings in the body wall, and passes directly to the internal organs.
