The life cycle of the spider mites

The eggs of the spider mites are laid on the leaves and bark of the host plants during the winter times. During the early springs, as the temperature goes up, the tiny larvae with 6 legs hatch from the eggs and start to feed on the plants for a few days. After some days, they seek shelter where they can molt into their first nymphal stage. Nymphs have the eight legs and before turning into complete adults they undergo two more molts.

After the mating process is completed, the female produces as much as 300 eggs for a couple of weeks. These pests prefer hot and dry weather for their fast and rapid development. If the conditions are favorable, then the egg may turn into an adult just in 5 days or less than that. Spider mites are also known as the windsurfers and they disperse over the wide areas with the breeze along with their webbings.
