Pheidole sciara

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Native to the American Southwest, west-central Texas to southwestern New Mexico, also found in northern Mexico. Inhabits open, sandy, semi-desert areas at elevations from 600 to 1700 meters ^[1][2].
• Colony Type: Based on Pheidole genus patterns, likely single-queen colonies, but specific data for P. sciara is unconfirmed.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pheidole genus that queens are approximately 6-8mm in length.
  • Worker: Size data unavailable, workers have major and minor castes, with majors larger than minors ^[2].
  • Colony: Colonies can reach hundreds of workers.
  • Growth: Moderate
  • Development: 6-8 weeks at warm temperatures. (Development time may vary with temperature and feeding.)
• Antkeeping:
  • Temperature: Keep at 24-28°C with a temperature gradient for self-regulation ^[2].
  • Humidity: Keep nest substrate lightly moist but allow drying between waterings, as this is a semi-desert species ^[2].
  • Diapause: Unknown, based on geographic range, winter diapause may be required, but not confirmed.
  • Nesting: Soil-nesting species. Use sandy substrate, Y-tong nests, or plaster nests with moisture chambers ^[2][1].
• Behavior: Pheidole sciara is peaceful but will defend the nest vigorously. Major workers use mandibles for defense. Escape risk is moderate due to worker size ^[2].
• Common Issues: colonies may fail if kept too humid, this is a desert species that prefers drier conditions., test tube setups can mold if water reservoir is too large and condensation builds up., slow founding phase can lead to beginner impatience, queens may take weeks to lay first eggs., ensure escape prevention is adequate, as workers are small and can fit through gaps.

Nest Preferences and Housing

Pheidole sciara naturally nests in soil in open, sandy desert areas, with entrances surrounded by small mounds ^[2]. In captivity, use a sandy soil mixture for natural digging or Y-tong nests with a thin substrate layer ^[2][1]. Provide a dry surface layer with moister substrate below for brood chambers to mimic their semi-desert environment.

Feeding and Diet

This species is omnivorous, preferring protein sources like small insects and seeds, with sugar available for energy ^[2]. Offer protein foods 2-3 times per week and remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Seasonal Care

Maintain nest temperatures between 24-28°C during active seasons using a heating mat for a gradient ^[2]. For diapause, if required, reduce temperatures to 10-15°C for 2-3 months in winter, but this is not confirmed for this species.

Behavior and Colony Dynamics

Pheidole sciara has major and minor worker castes, with majors handling defense and seed processing ^[2]. Colonies grow moderately, with first workers emerging 6-8 weeks after founding. This species is not aggressive toward keepers but defends the nest vigorously.
