parthenogenesis  (pärth-n-jn-ss)
Reproduction in which an egg develops into a new individual without being fertilized. Aphids and certain other insects can reproduce by parthenogenesis. Parthenogenesis does not necessarily produce clones of the parent. Among hymenopterans such as honeybees and ants, the haploid males develop from unfertilized eggs laid by the queen, who is diploid. Parthenogenesis is a form of apomixis.

The other likely cause, particularly with the mild, open weather that we had in late August and September, is a tiny little green or yellow aphid known as the Violet Aphid, Myzus ornatus, that builds its population up parthenogenetically (without mating) on the undersides of leaves of pansies and violas and these can destroy young plants very quickly, causing them to collapse and die in a matter of weeks.
For example, the whiptail lizard, which lives in the American Southwest, reproduces parthenogenetically (having no male contribution), and their colonies consist mostly of clones of females.
