They often are extremely variable in size and appearance within a given species (polymorphic = many forms: Figure 5), although some species have only one size of worker (monomorphic = one form), and others have two sizes (dimorphic = two forms). Six weeks to two months are required for development from egg to adult in some species. The mounds can reach records of about 5 m (~16ft) in diameter, especially with older nests found in fields and wooded areas.
