 Myrmecomorphy are arthropods that have evolved a morphological resemblance
 to ants. Ants - the
 model of Ants Mimicry 
                                                                              Ants
 are the most abundant group of insects and have powerful defense mechanisms such as acid
 taste, aggressive biting, painful sting, and group defense. Ants are generally
 not subject to predation. They are the ideal models in mimicry rings. Many insects
                                                                                   and spiders have
 different ways to resemble ants. This is known as Myrmecomorphy.

 in Katydid nymph - Family Tettigoniidae  We will never guess they are the first instars of the Katydids until we saw
 their development. They are dark brown and some are black in colour. They are
 quite large, about 10mm in body length. They just look like large black ants.
 This is an advantage to the young instars for most predators will avoid armed
 ants. They have very long antennae, about four times their body length. They
 are very active, running and jumping between plants. Details please click on here.

  Ant-mimic
 Bug - Family Lygaeidae   Yes, this is a true bug, Hemiptera. Its body colour and behaviour is mimicking the
 black ant. It was found wandering on a large gum tree trunk, where a lot of black ants is
 running around. It did not have the waist, which is the characteristic of all
 ants, but its body colour pattern mimics just exactly this. 
  Ant-mimic
  Bug Nymph - Pod-sucking Bug  The adult Pod-Sucking Bugs and different stages of instars on the Easter
  Cassia (Senna pendula) cylindrical seedpods. The small Pod-Sucking Bug
  nymph mimics black ants. 
  Ant-mimicking Longicorn Beetle  ? Ochrya sp. body length 20mm
  We saw this Ant-mimicking Longicorn Beetle once in Karawatha Forest during
    early summer. It was a cloudy day. The beetle was resting on a leaf until we
    disturbed it. It then slowing walked away. The patterns on the beetle's
    back made the beetle looked like a large black ant, with eyes on large head,
    narrow waist and round abdomen.
