In insects what does hemi metabolism indicate
ArbitrLikvidat [17]

The hemi metabolism<span> indicates the three distinct stages of the life cycle of some insects: the egg, nymph, and the adult stage, or imago. It has no pupal stage just like the complete metamorphosis that undergoes pupal stage before turning into adult. Insects that undergo hemi metabolous metamorphosis go through gradual changes; develop from eggs into nymphs sometimes called larvae by some entomologists, that are similar in shape to the adults. You can distinguish the nymphs from the adults by looking for wings. Wing buds or wing pads may be present in late stage nymphs, but they are fixed in place against the body and are non-functional compared to the adults whose wings are fully developed. </span>
