Thief ants are another one of the smallest species of ants (1-2 mm in length). Native to the United States, these yellowish-brown colored are equipped with large jaws for carrying food. These ants are known for stealing food from other ants, hence their name. Thief ants will build nests very close to other ant nests since their primary source is the other ant’s food source. Surprisingly, their nests are much larger and more spacious than what would be expected for such a small ant.
Unlike most ants, thief ants aren’t drawn to sweet foods, but rather greasy foods. Thief ant colonies can range from hundreds to thousands of ants. Some colonies are known to have up to 8 queens based on the colonies size.
