A few insects are ametamorphic and do not exhibit any metamorphic changes. The
aphids (Homoptera) are prime examples of this. An aphid is produced when an unfertilized egg
hatches inside the mother, grows to a young female that looks exactly like her mother except in
size, and the offspring emerges onto the host plant the mother is feeding on. After eating for
about a day, the young aphid has molted one or more times, and begins to produce her own
offspring
– even before she has reached full size or has finished molting. This mode of
reproduction is so efficient that under favorable conditions, an aphid colony can multiply to ten
times their numbers (1000%) in three days.
