Rusty brown color, blacked Gaster.

After gaining enough sperm to found a new colony, the queen will fly away from her old colony, up to approximately 11 km, shed her wings, burrow into the ground, and begin egg-laying. ADW doesn’t cover all species in the world, nor does it include all the latest scientific information about organisms we describe.

This page was last modified on 27 Decemberat The largest amount of food results in virgin queens, while slightly less food creates soldiers. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico.

One possible reason for this is, before the colony is established enough to sustain any large soldier-caste workers, it is useful to remain unnoticed. United States Fish and Wildlife Service. The largest of the ant castes, defenders usually have a head width above 3. The mated queen lands on the ground and tears off her now-unnecessary wings.


Prominent short hairs scattered on head, thorax and gaster more abundant. Another distinguishing feature is a relatively large, two-lobed head. Head width 3 mm. After suitable amounts of these workers have been born, the queen produces forager-excavators and within-nest specialists.

Collected most commonly using these methods: Once the leaf fragments are inside the nest each is prepared with a drop of anal liquid which acts as a fertilizer. There, ztta waste can decompose without endangering the ants. Thoracic spines pointed, shorter than the front mesonotal spines epinotal spines.

Postpetiole keeled, width 1, 3 mm, length 0, 8 mm. We encourage use of AntWeb images.

Check data from AntWeb. Rather than eat the fungus, she lives on her own fat reserves, eggs, and her wing muscles which she won’t need anymore.

Soldiers usually appear when the colony has a population of aboutThe purpose of these activities is to avoid infections, especially by parasitic fungi. This has two important results: In insects, sexdenz metamorphosis” is when young animals are similar to adults and change gradually into the adult form, and “complete metamorphosis” is when there is a profound change between larval and adult forms.

Atta ants also have a mutualistic relationship with their fungal crops. To answer this question, we evaluated the distance traveled by individual workers in the search of food and the distance traveled to return to the nest, as well as the time and velocity necessary for these activities.

Non-queen females cannot breed. How do workers search for their food? They cut leaves to provide a substrate for the fungus farms which are their principal source of food.
