text: are they complete or incomplete metamorphosis? do these insects go through complete or incomplete metamorphasis and what are their nymths called? example: fly- incomplete, maggot  cockroach sicadis bed bugs termites dragonflies beetles bees ants mosquitos insects that go through 'complete' metamorphosis are holometabolous and hemimetabolous insects go through 'incomplete' metamorphosis.  butterflies are the most well known holometabolous insects (order: hymenoptera) ie that have larval, pupal and adult stages. hemimetabolous species have a number of nymph stages (exoskeleton moults) after hatching from the egg. from your list cockroaches, cicadas, bed bugs (nasty), termites, dragonflies, beetles, bees and ants are hemimetabolous with only mosquitoes as holometabolous ie they have a riggler (larvae), pupae stage and adult comes out of the pupal case where it splits open along the back of the exoskeleton and the adult pulls itself out.
