Trichomyrmex destructor

Monomorium destructor has been updated to its senior synonym Trichomyrmex destructor (Jerdon 1851) This species is polymorphic having four main morphological expressions in its worker caste. Trichomyrmex destructor is also polygynous. It is a serious pest pest species with colonies causing serious damages to food stores.

Passive Aggression

 Trichomyrmex destructor workers strategically placing themselves all over a site to drive off Tapinoma melanocephalum from nesting in cracks of the same wall not far (around 40 centimeter) from where their nest.

 In this manner without actually attacking the Tapinoma they were able to drive them off. I caught this a little late and the main confrontation had already dissipated leaving just a small area (about a third) of the initial confrontation coverage and density by the time it took me to retrieve my camera from my residence and rushed down to take this shot. By the time I got back the Tapinoma had already mostly retreated and the Trichomyrmex coverage over the area was no longer as dense and only a third of the initial.

A close up of the left over confrontation.

Here Trichomyrmex destructor managed to drive off Carebara (Pheidologeton) ssp workers from a food find with the same passive-aggression strategy. Their strategy seems to be if they are attacked then only they attack back, biting and stinging. Solenopsis geminata too deploy a similar passive-aggressive strategy (they raise the gaster and secrete a tiny drop of venom) to protect and drive off other ants from their food find.
