Spiny Ant: The Ant Talk

Spiny Ant
Polyrhachis sp.

What might be these two ants conversing about?

These are slow-moving ants. Found them on the leaf litters and on the ferns and grasses that grows on the soil covered with these leaf litters. These formicine ants don’t have stings but the pain lingers even when you were just slightly stung buy one of those six sharp spines on their back, even the dead ones still have that effect. They’re about 10 mm in length, have  long antennal length, round eyes near middle of head,  one petiole with two spines  and four spines at the back of its thorax. They responded when they sensed vibrations and moved towards it with their abdomens tilted under their thorax. I wonder what preys them and how they were eaten with those stinging sharp spines.

The hard part of taking these photographs was enduring the red ants  biting my bare feet scattering all over the area while watching the other team of these spiny ants on  the leaf litters coming towards my poor feet.  I should have worn my shoes instead of slippers. I was just wandering near the camp but was led in their territory. Passing through a slippery and muddy slope trail before reaching this spot. In the end, the stings were worth it.  🙂

Order: Hymenoptera/ Family: Formicidae/ Subfamily: Formicinae/ Species: Polyrhachis sp.



Suborder Apocrita consisted of wasps, bees and ants, an Apocritan is distinguished by its petiole located between the two segment of its body, the thorax and abdomen. Wasps prey and parasitize on most of the pest insects, controlling the rise of their numbers.
