KIDS TRIVIA

Detailed explanation-1: -Apterygota are a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history. They include Thysanura (silverfish and firebrats).

Detailed explanation-2: -Juvenile insects never have wings. Adult insects are capable of reproduction but not of growth since no further moults are possible. Thus, a small insect with wings is a fully formed adult and will grow no further, whereas a large insect without wings may be a juvenile or, in some cases, a wingless adult.

Detailed explanation-3: -Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments.

Detailed explanation-4: -apterygote, broadly, any of the primitive wingless insects, distinct from the pterygotes, or winged insects.
