Reproduction and Development
Most insects reproduce sexually, although the aphids are a notable exception. Aphids reproduce by parthenogenesis, in which the egg develops into a new organism without fertilization . In honey bees and some other social insects, only one female per colony reproduces, and males are haploid , whereas females are diploid , a system called haploid diploid. The queen produces new (diploid) females (workers, soldiers, and future queens) from fertilized eggs. Males are produced from eggs that are not fertilized, and thus males are haploid.
