Flightlessness is often encountered where the energetic costs of flight are high (i.e. cold regions or areas of high winds). In many insect groups there is a trend toward increased brachyptery with increasing altitude and latitude.

Do flies eat blood?
Biting flies feed on blood, attacking humans and other animals as food sources. Some are capable of transferring disease through these feeding habits. There are many species of biting flies, each with its own habits and ecology.
Do some flies suck blood?
They can be quite bothersome, buzzing around a person’s head, especially where large numbers are present. Both deer flies and horse flies bite with scissor-like mouthparts that cut into skin, causing blood flow which the flies lap up. Because of this relatively crude means of obtaining blood, the bites can be painful.
Do ants have wings?
Ants with Wings
Only reproductive ants have wings, and they are winged and able to fly only during the breeding season. Ant species that do not swarm do not have winged members, and they increase their populations through budding.
Which insects Cannot fly?
Some insects, such as cockroaches, have wings but are reluctant flyers, preferring to crawl to find food and shelter. Termites and ants are mainly wingless, so most of their behaviour involves crawling, and produce ‘reproductives’ that are temporarily winged during a short breeding season.
What do you mean by wingless and primitively wingless insects?
Characteristics. The primary characteristic of the apterygotes is they are primitively wingless. While some other insects, such as fleas, also lack wings, they nonetheless descended from winged insects but have lost them during the course of evolution.
