Two-spotted spider mite
- Adult: Mite that is tiny and oval in shape. Ranges in color from orange-red to green to translucent. Body contents are often visible through the body wall, looking like two dark spots.
- Nymphs: Similar to adults but with four legs instead of eight.
- Eggs: Round, clear and attached to fine silk webbing on the undersides of leaves.
Timing of damage: VT to R5
Type of damage: Yellowing and defoliation of the leaves.
Scouting: Use a hand lens to check undersides of leaves for eggs, mites and webbing.
Economic threshold: One-third of the leaves on 50% of plants are covered with active mite colonies.
