Colony Life Stages

From precarious founding to senescent wisdom

The 90% Rule

Gordon's long-term studies revealed a sobering statistic: 90% of new colonies fail within their first year.

Young colonies face: predation, desiccation, resource scarcity, inability to respond effectively to threats. Only the survivors build the 20-30 year colonies we study.

Developmental Stages

  1. Founding (Year 1) — Queen alone, digging, laying first eggs. Extremely vulnerable.
  2. Ergonomic (Years 2-3) — First workers emerge. Colony grows but behavior is erratic.
  3. Expansion (Years 4-7) — Rapid growth. Foraging patterns stabilize.
  4. Maturity (Years 8-20) — Full size. Stable behavior. Produces reproductives.
  5. Senescence (Years 20+) — Colony may decline. Wisdom peaks.

Why Young Colonies Fail

  • Too few ants → statistical instability
  • Overreaction to stimuli → resource waste
  • No environmental memory → repeating mistakes
  • No superhighways → inefficient foraging

Application: Our Growth Gates

This is why we implement growth gates:

  • Gate 1 (10 ants): Prove concept
  • Gate 2 (100 ants): Prove architecture
  • Gate 3 (1,000 ants): Prove economics
  • Gate 4 (10,000 ants): Prove emergence
  • Gate 5 (100,000 ants): Prove stability

Each gate must be passed before scaling further. Wisdom comes from age, not haste.

"Only mature colonies reproduce. The colony must prove itself before it can create offspring."
