Incomplete metamorphosis - Some insects have to go through three stages of development: egg, nymph, and adult. The nymph and adult are similar in morphology, structure, and living habits. This development process is called incomplete metamorphosis. Such as locusts, cockroaches, crickets, cicadas, etc. Complete metamorphosis - Pterygota insects, such as various beetles, butterflies, moths, bees, and flies, after their insect bodies hatch from eggs, the larvae and adults are not only different in morphology, but also in lifestyle and living environment. From larvae to adults, they have to go through a pupal stage (which is not present in incomplete metamorphosis). During the pupal stage, the body undergoes a drastic transformation of tissues and organs. After the pupal stage, the adult emerges from the pupa. This is called complete metamorphosis, and most insects are of this type of metamorphosis. First the queen gives birth, and three days later it hatches like an egg, then the snail spits out royal jelly, which seals the cap, and soon it breaks through the skin and swims out. After a few days, it can go out to collect honey. |
