Males are about 3mm long, black, winged (but do not fly). This success can be attributed to their efficient foraging strategy, and their novel use of venom alkaloids, repellant chemical signals. In this way, the colony has a cushion against food shortages. [13] Despite their extreme importance, there is an adaptive value to using pheromones sparingly, as it streamlines communication during important decision-making situations, such as a nest migration. But this belief is a mistaken belief and the name of these ants has not connection with its meaning. The teeth ensure sex lasts long enough for sufficient sperm transfer.

The decision to vary the type of food consumed ensures that the colony maintains a balanced diet. The penis valve contains sharp teeth, which latch onto a thick, soft cuticular layer in the female. Colonies proliferate by "budding"[3] (also called "satelliting" or "fractionating"), where a subset of the colony including queens, workers and brood (eggs, larvae and pupae) leave the main colony for an alternative nest site. They can also gnaw holes in silk, rayon and rubber goods. How to Get Rid of Pharaoh Ants in an Apartment.
