Spider mites have rasping–sucking mouthparts. Feeding damage appears a light–colored spots, or stipples on upper leaf surfaces. Spider mites also produce webbing. Heavy infestations can kill plants or cause leaves to drop off, and webbing can cover leaves and flowers resulting in aesthetic injury.

Spider mite developmental stages are egg, larva, protonymph, deutonymph, and adult. Development from egg to adult takes about 8 days (77?–95?F, 25?–35?C) to 28 days (50?–68?F, 10?–20?C). Hot and dry conditions are most favorable. Spider mite development is affected by the host plant, plant nutrition, leaf age, and moisture stress. Moisture stressed plants often have higher spider mite populations. High moisture slows mite dispersal. Spider mites are usually on undersides of leaves, but may be on/in flowers in heavy infestations.
