Hemimetabolizmusnál

Hemimetabolizmus is a type of insect development where immature stages, called nymphs, gradually transform into adults. This process involves incomplete metamorphosis, meaning there is no pupal stage. Nymphs typically resemble smaller versions of the adult insect, but they lack fully developed wings and reproductive organs. They undergo a series of molts, shedding their exoskeleton to grow. With each molt, the nymphs become larger and their wing buds become more prominent. This development continues until the final molt, at which point the insect emerges as a fully winged, reproductively mature adult. Hemimetabolous insects include orders such as Orthoptera (grasshoppers, crickets), Hemiptera (true bugs, cicadas), Odonata (dragonflies, damselflies), and Blattodea (cockroaches). The environment in which nymphs live can vary; some, like mayfly nymphs, are aquatic, while others, such as grasshopper nymphs, are terrestrial. This mode of development contrasts with holometabolous insects, which undergo complete metamorphosis with distinct larval and pupal stages.
