Recognizing spider mites:

mites are not insects but arachnids, so small spiders. When they mature, they have four pairs of legs, the younger stages have three pairs of legs. They have no antennae; most insects do have antennae. Best known is the two spotted spider mite, gray-green colored with two dark spots on the flanks; in winter their color may turn darker. Eggs they usually deposit on the underside of leaves, often protected by silken threads. During heavy infestation plant tips can by completely covered by this silken webbing. Apart from two spotted spider mites one may find other types of red mites, such as false spider mite, citrusmite or fruit spidermite.

False spidermites:

These tiny red mites mainly occur on leaves of a number of plant species. They hardly move, sitting quietly along the veins on upper or underside of leaves. You need a good magnifying glass to be able to see them. They can cause a lot of damage: rust brown coloration of the plant tissue, at first along the veins but later the whole leaf may become infested with leaf fall as a result. These are false spider mites.

Tarsonemid mites: 

This is a completely different group of mites that we find especially in the upper part / growing tip of the plants. The mites themselves are too small to be seen by naked eye, they can only be seen with a magnifying glass. The damage is clearly visible: leaf distortion in the tip of the plant and in severe infestation situation atrophy of the upper leaves, severe growth inhibition and even leaf drop. The mites themselves are very small and transparent. Their mobility is rather limited so the mites tend to aggregate together in large numbers, often hidden for some time among young folded leaves.

mite characteristics:

  • small, less than 1 mm
  • adults with 4 pairs of legs
  • young stages three pairs of legs
  • no antennae
  • yellow / green to dark or red
  • some species transparent
  • sometimes eggs in silken webbing

mite damage:

  • starts at underside of leaf
  • spots on leaves, leaf discoloration
  • leaf desiccation and leaf fall
  • silken threads with eggs
  • growth inhibition in tips
