Spider Mite
Tetranychus spp. (e.g., Tetranychus urticae, Two-spotted spider mite)
- Order & Family
- Order: Trombidiformes, Family: Tetranychidae
- Size
- 0.2 to 0.7 mm (very small, barely visible to the naked eye)
Natural Habitat
Spider mites are found on a wide variety of plants, including agricultural crops, ornamental plants, garden plants, and houseplants. They thrive in warm, dry conditions and can be found both indoors and outdoors.
Diet & Feeding
Spider mites are plant feeders. They feed by piercing plant cells with their mouthparts and sucking out the contents. This feeding causes characteristic stippling (small dots) on leaves.
Behavior Patterns
Spider mites are tiny arthropods that are known for spinning fine silk webs on plants. They live in colonies, usually on the undersides of leaves. They reproduce rapidly, especially in hot, dry conditions. Their life cycle from egg to adult can be completed in as little as five to seven days.
Risks & Benefits
Risks: Spider mites are significant agricultural and horticultural pests. Their feeding can cause severe damage to plants, leading to reduced photosynthesis, leaf discoloration, defoliation, and even plant death in heavy infestations. They do not pose direct risks to humans or animals. Benefits: In certain ecological contexts, they can serve as a food source for predatory mites and other beneficial insects. However, their pest status far outweighs any perceived benefits for humans.
