Question

Which of the following insects are wingless?
A. Pediculus
B. Cimex
C. Lepisma
D. All of the above

Answer 1

Hint: Many insect communities do not have wings, so wingless subsets are unexceptional. Many wingless insects are representatives of insect species that normally have wings.

Complete step by step answer:
i. Lice (Pediculus) are small wingless, flattened bugs with three body parts namely; the head, the thorax and the abdomen. Every development model of head lice could be attached directly to or gripping the head hair, particularly just at the neck area and behind the ears. These are intensely site-specific and have always been implanted to other body areas to try to migrate back to head.
ii. Bed bugs are insects that belong to the genus Cimex. They feed on the blood of humans, particularly at night. It might have a range of health consequences, including skin infections, psychological impact, and allergy signs. The bugs are 3 to 9 mm long and also have flat reddish-brown structures with small defective wings (that do not work).
iii. Silverfish (Lepisma) is a tiny, wild, wingless bug. The general term derives from the silvery, pale grey colour of species, associated with the fish-like image of its gestures. Silverfish eat substances possessing polysaccharides, like starches and dextrin in coatings.
So, the correct answer is option D.

Additional information: The female lice deposit their nests called nits, mostly on the host's hair itself or on the body. Lice are passed from one person to another by touch directly, by a comb, or by the fallen hair. Cimex is drawn to its hosts primarily by carbon dioxide, secondarily by heat, and by certain chemical compounds. Bed bugs love bare skin, particularly a sleeping individual's face, hands, and arms. Silverfish are regarded as household pests owing to their consumption and devastation of assets.

Note: There are a lot more insect species that lack wings. Some insects that do not have wings can belong to insect groups whose ancestors once had wings but could have lost it due to growing evolution. On the other hand, some ancestral groups like Lepisma never had wings. Some would have lost their wings because of the way they have practised to live.
