Morris’ Big-Headed Ants (Pheidole morrisii)

General: Pheidole morrisii is a yellow, medium sized, fast growing species of Pheidole from the eastern US. These ants are very fun and get lots of majors!

Diet: These Pheidole do not prefer seeds, but rather sugary liquids and general protein. They accept a wide range of protein, such as crickets, mealworms, roaches, and fruit flies. It is recommended to feed them frequently.

Temperature: These ants require heating. Their nest should ideally be between 80-86, but provide a heating gradient if possible. Pheidole morrisii will not grow much, if at all, at room temperature.

Diapause: Pheidole morrisii usually doesn’t need diapause. However, if your colony seems to slow down during the winter, simply diapause them at room temperature or lower for 1-3 months. It is not recommended to let the nest temperature drop to near freezing.

Growth: Brood development takes 4-6 weeks depending on heating and caste. The majors tend to take slightly longer to develop. Colonies can reach over 1000 workers within the first year if fed lots and heated correctly. Majors typically show up in the 2nd or 3rd generation.

Queen size: 8-10mm

Worker size: 3-3.5mm

Major size: 4-4.5mm
