Pheidole obtusospinosa (Desert Big-Headed Ant)

Pheidole obtusospinosa — one of the most remarkable big-headed ants you can keep. This desert Pheidole is famous for a rare third worker caste: enormous “supermajors” that use their oversized heads to physically block the nest entrance against invaders.

• You'll receive: a fresh-caught queen with advanced brood — well on her way to her first workers.
• Founding: Fully claustral — she raises her workers sealed away.
• Diet: Seeds (granivore) plus plenty of insect protein.
• Castes: Minors, majors, and rare head-blocking supermajors.
• Range: Sonoran & Chihuahuan deserts of the American Southwest.
• Difficulty: Intermediate — fast-growing and protein-hungry.

Very limited — only a couple of queens available.
