Formica neoclara

This species nests in the soil, usually with a mound. Sometimes nests are located at the base of a plant or under stones or logs, or in stumps, often in sandy soils. Nests can be large, with a circumference over 9 meters in diameter, with over 125 entrances. (Mackay and Mackay 2002)

Identification
Usually a light yellowish brown with a gaster that is only slightly darker. Occasionally workers are red with a black gaster, or even nearly black, with yellowish-brown areas. The pilose lobes on the metasternum are not always well developed, but there are always at least a few golden erect hairs on the posterior edge. (Mackay and Mackay 2002)

Distribution
Western North America from Yukon Territory, Canada south to northern Mexico.

Distribution based on Regional Taxon Lists
Nearctic Region: Canada, United States. Neotropical Region: Mexico.

Habitat
In New Mexico (Mackay and Mackay 2002) - Residential areas, grasslands (including arid grasslands) and open deciduous woods, oak forests, pinyon juniper into pine and fir forests.

Biology
Populous colonies common in grasslands, open woods, and especially in disturbed areas. The nest is usually exposed and surmounted by a low messy mass of excavated soil, which often covers a considerable area, e.g., 90-120 cm x 60-90 cm and always with many entrances. These ants have often been reported tending aphids. Abundant in some nests has been Uhleriola floralis (Uhler) (Hemiptera: Lygaeidae), a bug that resembles the ants (Wheeler and Wheeler, 1963:271).

For New Mexico (Mackay and Mackay 2002) - Brood was collected in June to August. Reproductives were found in nests in July and August, dealate females were collected in late June and July. This species may be polygynous, 3 dealate females were found in a single nest. Foragers are often found on cholla (Opuntia imbricata var. arborescens). Workers may be aggressive when a nest is disturbed, although they usually escape. This species is enslaved by Polyergus breviceps and nests with Camponotus modoc.

Nevada, Wheeler and Wheeler (1986) - Our 17 records are from 12 localities which are widely scattered throughout the state; 3,900-9,800 ft. Three records are from the Cool Desert (1 from a disturbed riparian habitat and 2 from a cottonwood grove in an irrigated farmyard) and 4 were from the Coniferous Forest Biome. One exposed nest was surmounted by a 75-mm crater, 1 by piles of excavated earth along exposed cottonwood roots; 1 was in soil at base of a cottonwood stump; 2 were under stones; 1 was in and under a rotten log; 1 was under buried wood. We noted fast moving processions of workers up and down cottonwood trunks.

This species is a host for the slave-making ants (Mackay & Mackay, 2002),,  (Trager, 2013; de la Mora et al., 2021) and  (Trager, 2013; de la Mora et al., 2021).
