Manica mutica

Medium-sized, entirely orange-red ant. Very similar to harvester ants in color and appearance, but more slender and move more slowly. Colonies tend not to forage on hot days, so in the middle of summer they are most active in the morning and evening. Colonies have small, inconspicuous nest openings. If the colony is not foraging, wind tends to obliterate nest openings, leaving no sign of a nest. Unlike harvesters, these ants actively climb into plants and appear to be taking nectar or plant sap (Nonacs).
