Question

An insect without pupa stage is?
A.Mosquito
B.Butterfly
C.Silk Moth
D.Bed Bug

Answer 1

Hint: Pupa, plural pupae or pupas, is a life stage during insect development, showing the complete metamorphosis that occurs between the larval and adult stages (imago). During the up period, the larval structure is broken and the adult structure like wings appears for the first time

Complete answer:
Silk Moth: Before metamorphosis occurs, many silkworm moths spin cocoons around themselves. Commercial silk is produced by the domesticated silkworm moth caterpillar Bombyx mori. B. mori does not live in the wild, in fact it cannot survive in the wild because adult moths cannot fly.
Butterflies: often have brightly colored wings with unique patterns made up of tiny scales. Scientists estimate that there are between 15000 and 20000 different species of butterfly. Birdwing butterflies have large, angular wings and fly in a similar way to birds. Monarch butterflies are known for their long migration.
Mosquitoes: attracted by certain compounds present in human skin and sweat. These compounds give us a special smell that can attract mosquitoes. Several different compounds are attractive to mosquitoes. Some substances you may be familiar with include lactic acid and ammonia.
Bed bugs: It is generally believed that travel is the most common cause of bed bugs. Travelers usually don't know that bed bugs will hitchhike, step on people, clothes, luggage or other personal items, and accidentally transport them to other places.

Hence the correct answer is OPTION(D)

Note: Their life cycle involves eggs, nymphs and adults. The nymphs are newly hatched larvae, and reach adult stage after several times of metamorphosis. The life cycle of a mosquito involves eggs, larvae, larvae, and adults. The life cycle of silkworm moths involves cocoons, moths, eggs and larvae. The life cycle of a butterfly involves eggs, caterpillars, and butterflies.
