They are not insects but arachnids, belonging to the same class as spiders and ticks. The webspinning spider mites, so called because of the web they build, include the Pacific spider mite, two-spotted spider mite, strawberry spider mite, and several other species. Unlike insects, mites do not have antennae, segmented bodies, or wings.
Adults have eight legs and an oval body, with two red eyespots near the head end of the body.
Monitoring Inspect the undersides of leaves, particularly along the main ribs, for diffused webbing. Check middle-aged leaves first, since mite infestations seems to begin on such leaves. Hold a sheet of paper beneath the plant and tap the foliage sharply. Inspect the paper for rapidly moving dislodged mites. Damage Mites puncture plant cells with their mouth-parts, then suck the exuding fluids.
