Messor pergandei is a species of harvester ant native to the Southwestern United States, especially the deserts of southeastern California. It has also been identified in the Baja California peninsula of Mexico.[1] It was first described by Gustav Mayr, who named it Aphaenogaster pergandei.[2] It has also been referred to as Veromessor pergandei[1] when classified in the Veromessor genus (a junior synonym of Messor).[3] It can also be referred to as a black harvester ant or desert harvester ant, although these common names have also been applied to other species.[4][5]

Description

M. pergandei has a head of equal length and width, with very large mandibles. It has short white or yellow hair and a large thorax. Males typically measure about 8.5 mm (0.33 in) and females about 10 mm (0.39 in).[1] However, individual size can vary based on factors such as availability of food and interspecific competition.[6]

Ecology

Like other harvester ants, M. pergandei gathers fruits and seeds for food. The seeds of perennial shrubs such as Larrea tridentata and Ambrosia dumosa are included in its diet.[7]
