The sharp, and powerful mandibles of this Acromyrmex versicolor worker can be seen clearly in this image. These cutting and grasping tools allow the ants to efficiently remove large amounts of vegetation from a wide variety of plants. The freshly cut plant material is then brought back to the nest where it serves as a medium for the growth of a nutritious, symbiotic fungus.](http://www.pogolumina.net/Other-ants/Acromyrmex/i-27vNsCV/1/Ti/6251_10_7D-Ti.jpg "pogolumina > ● Catalina State Park, Tucson [Pima Co], AZ USA [el. 800 m / 2625 ft] view location in Google Maps »

Climbing over many obstacles on her way back to the nest, this A. versicolor worker carries a mesquite leaflet. Leafcutter ants (of many different species) often transport their cargo in this manner; grasped in the mandibles, with the object held backwards over the ant's body. Because of this, leafcutters are often referred to as 'parasol ants'.](http://www.pogolumina.net/Other-ants/Acromyrmex/i-ssfMm67/0/Ti/6257_10_7D-Ti.jpg "pogolumina > ● Catalina State Park, Tucson [Pima Co], AZ USA [el. 800 m / 2625 ft] view location in Google Maps »

Despite their fearsome appearance, these Acromyrmex versicolor workers are not known to readily attack human investigators. One can observe or photograph them at length, with little or no sign of an aggressive or defensive reaction from the ants. Other leafcutters, such as certain Atta species, can and will slice through skin with their enormous mandibles.](http://www.pogolumina.net/Other-ants/Acromyrmex/i-LrfLxV7/0/Ti/6288_10_7D-Ti.jpg "pogolumina > ● Catalina State Park, Tucson [Pima Co], AZ USA [el. 800 m / 2625 ft] view location in Google Maps »

In addition to their foraging activities, Acromyrmex versicolor workers also spend a great deal of time on nest maintenance, and construction. In this image, a major worker carries a small pebble up to the top the the volcano-like nest structure. Many tunnels, galleries, and fungus-growing chambers are hidden in the subterranean portions of the nest. A tiny minor worker is seen here as well.](http://www.pogolumina.net/Other-ants/Acromyrmex/i-28vzrwz/0/Ti/6693_10_7D-Ti.jpg "pogolumina > ● Duval Mine Rd, Sahuarita [Pima Co], AZ USA [el. 882 m / 2893 ft] view location in Google Maps »
