Latin Name: Atta sexdens. Trivialname: Leafcutterant. Taxonomy: Subfamily: Myrmicinae Tribe: Attini. Keeping Level: (3) through their large Space- and. Atta sexdens, along with A. cephalotes, is the most widespread member of its genus. Its northern most range is Mexico, and extends through Central America. Atta sexdens: leafcutter ant: cubic feet), a colony of A. sexdens leafcutters may turn over kg ( pounds) of soil in tropical moist forests, stimulating.
During their nuptial flights, the queens mate with several males, which die shortly after. Herzfoermig head, posterior margin strongly bulged. At first, the colony grows slowly, but after two to three years, the sexdenz becomes faster.
Referring to a mating system in which a female mates with several males during one breeding season compare polygynous. After the first 2 years, the colony grows in leaps and bounds, and sexually active queens and ssxdens appear. Atta sexdens is an aggressively territorial species. From this point, all four castes of ants may appear in the queen’s eggs. Thoracic spines pointed, shorter than the front mesonotal spines epinotal spines.

In addition to the fungus, the A. Epinotal spines judged longer than the Mesonotal zaehne, but shorter than their mutual distance at the base, straight back. sexvens
Leaves and other soft plant material brought into the nest by the foragers is chewed into a pulp and fertilized with faeces. Fertilized eggs produce females. Legs covered with short oblique. Feceshowever, are not carried away, but used to fertilise the fungal gardens. These insects include flies of the family Phoridae which lay their eggs on foragers.
Smaller workers sometimes ride on the leaf pieces while the foragers carry them. Usually, the garden is fertilized only with feces, but sometimes it is necessary for the queen to forage a small quantity of plant material.
In fact, Atta ants are considered the number one herbivorous pest in many areas where they are found. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts.
Queens may produce up to million daughters during their lifetime. In insects, “incomplete 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.
From Wikipedia, the free encyclopedia. Long hair on the head and gaster, shorter thorax, scattered pubescence. The purpose of this behavior is not known for certain, but may be to protect the exposed foragers from attacks by parasitic insects. Eidmann – The springtail species Seira edmanni Stach Seiridae is known from nests of this ant. Unfertilized eggs will turn out to be males, which are strictly used for mating and are short-lived.
Queens of Atta sexdens are the only females that mate.
The gaster, the organ used for applying these chemicals, can be used to mark cut leaves, cutting sites, territory boundaries, and paths to take to get to cutting sites or rubbish heaps. The fungus provides different types of nutrition to the ants, and the ants feed the fungus and protect it from parasitic fungi genus Escovopsis.
Some researchers believe all fungus-growing ants cultivate just one species, Sexdwns gongylophorus.
By this time, the original colony has likely sent sexcens several mating flights’ worth of queens to populate other areas and propagate their genes. Thorax length 5, 4 mm.
Atta sexdens – Wikipedia
The diameter of the colony may reach 10 m with a depth of 6 m. All female eggs are identical when laid.
Atta sexdens is a considered a serious pest throughout its range, causing damage to a wide variety of agricultural crops and ornamentals Cherrett, Rather than building upward, A. A small piece of fungus is placed on this substrate. In that time, the colony will have sent srxdens numerous males and virgin queens to found new colonies. This has two important results:
