Harvester Ants Harvester Ants Pogonomyrmex spp. The harvester ants are large ants 5 to 6 mm in length and different species can vary in color from reddish-brown to yellow or black. They have elaborate fringes of hairs underneath the head.
Winged ants have two pairs of wings, the anterior pair being much larger than the second pair.
The eggs are minute, less than 0.5 mm long, white and elliptical in shape. The body is covered with short hairs and is shaped like a crookneck squash or gourd with a small distinct head. The so-called harvester ants occur west of the Mississippi except for one species. The two most common species are the Texas harvester ant and Western harvester ant. The harvester ants do not consume grass for food but denude areas around mounds and along trails.
