Spider Mites
Tetranychus urticae

  • Feeding on the underside of leaves causes a “russet” appearance to the leaves; leaves may become distorted
  • In heavy infestations, webbing can be found on underside of leaves
  • Adult spider mites are very small (approximately 1/50 inch in length), and are yellow to dark crimson, with dark spots
  • Mites usually appear in late June-August; more prevalent in hot, dry weather
