Life cycle and appearance of Spider mite

Two-spotted spider mites (Tetranychus urticae) pass through the following developmental stages: egg, larva, protonymph, deutonymph, and adult. In the larval and nymphal stages, an active period and a resting period of roughly equal duration can be distinguished. Eggs are usually found on the underside of leaves. They have an oval body that is rounded at the rear end. Their colour can vary from orange, light yellow or light green to dark green, red, brown, or almost black.
