Leafcutter Ant Distribution

Home ---> Leafcutter Ant Distribution

(en español)

My research on the worldwide distribution of leafcutter ants. I'll add more information as time passes. If you know of any other distribution patterns for the leafcutters, please email me.

Atta texana

Along the FM 1078 road corridor (right of way) and an area of regeneration north of camp Tonkawa, located in northern Nacogdoches and southern Rusk Counties, 10 km west of Garrison, Nacogdoches County, Texas, USA D.L. KULHAVY, L.A. SMITH, and W.G. ROSS, Impact of the Texas Leaf-Cutting Ant (Atta texana (Buckley)) on a Forested Landscape
Circa 1950. "Largely confined to south central Texas. A line drawn from houston through austin and san antonio and thence south to brownsville would include the majority of the records. (it) undoubtedly occurs in northeastern Mexico, although there is too little data at present to determine the southern limit of the range. It seems, however that, unlike several other species which range northward from Mexico and into the gulf states, A. texana does not occur east of Texas, although there are areas in Louisina and Mississippi which appear suitable for it."

Circa 1907. Wheeler in USA: "I have found no indications of its occurence outside of a rather restricted area in Texas. The area seems to have its center at Austin and to comprise the territory for some hundreds of miles north and south in a narrow belt where there is a moderate annual rain-fall and where the forests are of a mesophytic character. I have never seen it in the dry western portions of the state nor have I heard of its occurence in the more humid eastern counties, in Lousiana, or the other Gulf States. It was seen as far south aa Alice in Nuces county and probably occurs as far north as Waco and Fort Worth. It certainly could not endure the winters of the "Panhandle" region nor even those of the extreme northeastern portion of Texas. Even in the vicinity of Austin, large colonies are rather sporadic. It prefers the neighborhood of rivers and creeks and especially the rich soil of the pecan abd the pure sand or somewhat clayey soil of the post-oak woods. In such spots one is always sure of finding it along the banks of the Colorado, Comal, and Guadaloupe rivers."

Acromyrmex volcanus

Acromyrmex volcanus is common in mature wet forest on the Atlantic slope of Costa Rica, occurring from sea level to about 1000m elevation. It is one of the most common and conspicuous attines in lowland primary forest, giving way to Atta in second growth and more open habitats. At La Selva Biological Station, A. volcanus workers forage on the ground but nests are arboreal. Jack Longino's Costa Rican Ants website
