Pheidole bicarinata, the Common Big-Headed Ant is a species of ant in the genus Pheidole.[1][2] It is distributed across United States, from Nebraska, Colorado, Texas, Utah and Nevada, east to New Jersey and Florida.[3] It is found in a wide range of habitats.[4][5]
Diet
[edit]Pheidole bicarinata are known to eat insects, collect seeds, and consume nectar from extrafloral nectaries.[2][4] Seeds consumed include the seeds of Poa pratensis, Taraxanum officinale, Oenothera biennis, and more.[2]
Development
[edit]Colonies of Pheidole bicarinata grow quickly in captivity. They are noted to reach up to 4000 workers but rarely exceeding that number.[2] Pheidole bicarinata has four larval instars.[4]
