 The phoretic mite "Planodiscus" (Uropodidae) appears to exploit tactile or Wasmannian mimicry.The mite attaches itself to the tibia of its host ant, "Eciton hamatum".The cuticular sculpturing of the mite's body as seen under the electron microscope strongly resembles the sculpturing of the ant's leg, as do the arrangements and number of the bristles (setae).
