What is the wormlike stage of insect development after the egg?
A
Pupa
B
Maggot
C
Grub
D
Larva
Explanation: 

Detailed explanation-1: -Larva: the second, “worm-like” stage in the life cycle of insects that undergo complete metamorphosis (like caterpillars). Pupa: resting stage during which tissues are reorganized from larval form to adult form.

Detailed explanation-2: -When the immature insects and the adults have different forms, the process is called complete metamorphosis, and the worm, or grub, like juvenile insects are called larvae.

Detailed explanation-3: -Eruciform larvae are caterpillar-like and have a cylindrical body and well-developed thoracic legs, and prolegs are present. Finally, vermiform larvae are “wormlike.” It is generally applied to an elongate, legless larva with or without a conspicuous head.

Detailed explanation-4: -About 75% of all insect species go through the four stages of complete metamorphosis-egg, larva, pupa, and adult. The larva is a specialized feeding stage that looks very different from the adult. Fortunately, there are just a few basic larval types and they are relatively easy to recognize.

Detailed explanation-5: -Larvae undergo metamorphosis, transitioning to benthonic postlarva or juveniles3. Complex morphological and physiological changes occur during the transition between these stages, and morphological differences in the larvae development of gastropods have been reported4, 5, 6.
