Ans: In a complete metamorphosis the larvae are very different from the adult. The larvae are at the feeding stage, then you go to the pupil stage and the pupae can vary tremendously. Sometimes it can be hard and brown pupae or it could be in a silken cocoon, a lot of different characteristics. Then in the final molt stage, they become adults with wings. The pupal stage is generally inactive, but if you look very closely in pupae, it is a little bit warm outside. The adult stage tends to be the reproductive stage, very often with some of these the adults don’t even feed or not. Particularly aggressive feeders, for this it is a good example is a butterfly or moth. We know that caterpillars or larval stages will consume a lot of plant material. But in fact, the butterfly might just need a little bit of nectar and not be any kind of pest problem at all. Very different feeding between the different stages can be observed. An example of the insects that have complete metamorphosis are bees, moths, ants, beetles, mosquitoes, and flies, these tend to be the more advanced in the insects.
