Atta texana is a fungus-farming ant species of the genus Atta, found in Texas, Louisiana and northeastern states of Mexico.[1] Common names include town ant, parasol ant, fungus ant, Texas leafcutter ant, cut ant, and night ant. It harvests leaves from over 200 plant species, and is considered a major pest of agricultural and ornamental plants,[2] as it can defoliate a citrus tree in less than 24 hours. Every colony has several queens and up to 2 million workers. Nests are built in well-drained sandy or loamy soil, and may reach a depth of 6 m (20 ft), have 1000 entrance holes, and occupy 420 m2 (4,500 sq ft).[1]

Description

A. texana workers measure 4 to 14 mm (0.16 to 0.55 in) in length, and are highly polymorphic. The back of the thorax has three pairs of spines. The ant has a narrow waist and is rusty brown in color.[1]
