How many sets of wings does a housefly have

The housefly's thorax features all of its limbs used for movement. Though flies appear to have only one pair of wings, closer inspection reveals the presence of tiny, secondary wings, called halters, located below the main pair.

While their ancient ancestors boasted two full sets of wings, houseflies have learned to do more with less. Over millions of years, the lower set evolved into the shrunken appendages you see today. They're far from useless, however. Houseflies flap their halters at high speeds during flight, using them to maintain balance in the air. If one halter is removed, the insect can only fly in circles. Without either halter, the fly can't take to the air at all.

The primary wings do the rest of the work, beating 200 to 300 times a second for an average speed of 4.5 miles (7.24 kilometers) per hour. The wings provide enough power and precision for instant liftoff and complicated flight movements, such as tight spirals, zigzags and even backward maneuvers.

And then there are the legs, which the fly uses to taste everything it lands on. Tiny hairs on the end leg segment, or tarsi, work like human taste buds. For this reason, you can often spot houseflies walking around in circles on potential meals.

Hint: Insects develop wings from the exoskeleton as a result of adult maturation. They are found on the second and the third thoracic segment or commonly called mesothorax and metathorax. This enables the flies to fly.

Complete answer:
> Option A:
Dragonflies have two pairs of wings and are similar in size. In order to fly, dragonflies angle their body upward like a helicopter and fly backward and use their wings to pull their body backward with an appropriate amount of force. Their wings are mostly composed of veins and membranes that give a complex and versatile design to the wings of dragonflies.

> Option B:
Housefly has two wings or one pair of wings as it belongs to the order Diptera. The hind pair is reduced to the halteres that are used for balance and flight stability by flapping the halters. The wings of the housefly are yellowish and translucent. The lobe, calypter at the back of the wing covers the haltere. The fly can only fly in circles if the haltere is removed.

> Option C:
Mayflies have two pairs of wings but unlike dragonflies, they are not similar in size. The hind wings of the mayflies are smaller than the forewings. They may be vestigial or may be absent. They have triangular membranous wings that are covered with veins. The second segment of the thorax bearing forewings is enlarged to hold the flight muscles.

> Option D:
Butterflies have four wings or two pairs of wings, two on each side divided into two forewings and two hindwings. The wings are attached to the second and third thoracic segments (the meso- and meta-thorax) that enable the flies to fly. The wings move up and down in a figure-eight pattern when the butterflies take a flight. Butterfly wings are made up of two chitinous layers (membranes) and are covered by thousands of colorful scales and hairs.

Hence, the correct answer is option (B).

Note: Halteres can rapidly oscillate along with the wings and work like operating structures and the insect uses this vibration as a sensation to locate themselves in the space. Like houseflies, horseflies, crane flies, and hoverflies also have one pair of wings.

How many sets of wings does a fly have?

Though flies appear to have only one pair of wings, closer inspection reveals the presence of tiny, secondary wings, called halters, located below the main pair. While their ancient ancestors boasted two full sets of wings, houseflies have learned to do more with less.

Do house flies have 4 wings?

IDENTIFICATION. The order Diptera is composed of the “true flies,” and is one of the largest groups of insects. Diptera means “two wings.” True flies have only two wings (one pair), instead of four wings (two pair) found in most other types of winged insects.

Does a housefly have wings?

Flies have a pair of fully developed wings on the thorax, and a knobby, vestigial second pair of wings, called halteres, that are used primarily for balance. The fly's six legs also connect to the thorax and are made of five segments. The housefly has a hard exoskeleton that protects it from moisture loss.

Why do flies have 2 wings?

Most flying insects have two pairs of wings (think of a dragonfly). In flies, the second pair of wings has evolved into special organs used for orientation in flight. These organs are called "halteres", and they function as balancing gyroscopes. All flies have halteres, including fruit flies and house flies.
