In polymorphic ants worker size is phenotypically plastic where eggs of a single genotype are responsive to environmental stimuli and result in alternative phenotypes This plasticity has potentially contributed to ant diversi?cation and speciation (93) and their ecological success (84)
Polymorphic workers range in size from 6 to 13 mm which distinguishes them as one of the largest ant species Colonies are usually found in logs trees or some other wooden structure Workers forage for dead or live insects honeydew or common household foodstuffs
What are the characteristics of polymorphic ants?
These large polymorphic ants (4–9 mm) possess a notch or depression on top of the thorax. Many colonies have multiple queens. Colonies usually nest in soil or in rotten logs. Frequently these ants make a thatch or mound of plant material, often grass.
What is the largest ant species?
Polymorphic workers range in size from 6 to 13 mm, which distinguishes them as one of the largest ant species. Colonies are usually found in logs, trees, or some other wooden structure. Workers forage for dead or live insects, honeydew, or common household foodstuffs.
What does a western thatching ant look like?
Many species of western thatching ant (Fig. 16) are bi-colored, red and black; some species can be uniformly brown or black. These large polymorphic ants (4–9 mm) possess a notch or depression on top of the thorax. Many colonies have multiple queens. Colonies usually nest in soil or in rotten logs.
How do ant colonies grow?
Many ant colonies are started by a single inseminated female, called a queen. From this single individual, ant colonies can grow to contain anywhere from several hundred to millions of individuals.
