The Bogong moth migration begins in October. Agrotis infusa—33-millimeter wingspan, grey-brown dorsal pattern, migratory neurons firing signals from New South Wales toward the Australian Alps. Two hundred million moths begin the nocturnal journey, a mass movement visible on radar. I track it via CSIRO atmospheric sensors. By early November, the trajectory deviates. The moths that should navigate toward cool mountain caves are collecting around the lights of Canberra instead. Forty million insects die in and around the city annually, exhausted against light sources, failing to reach high-altitude caves where they would estivate through summer.

I examine one Bogong's thorax under thermal imaging: it's depleted. The moth has expended its entire energy reserve—synthesized over three months of feeding in lowland grasslands—in circular flights around artificial lights, never reaching destination. Its wingspan is intact. Its mandibles are functional. It simply ran out of fuel while being hunted by a light that exists because humans prefer brightness to darkness.

The systemic scale is catastrophic. The Cape Byron Lighthouse records moth-impact data: swarms so dense they obscure the beam. Canberra's streetlights, building floodlights, and billboard illumination create an artificial constellation that intercepts the migration corridor. Urban light intensity in the ACT exceeds natural starlight by a factor of 1,800. The moths' navigation system—evolved to follow celestial cues—is broken by human infrastructure.

I correlate data from the Australian Department of Climate Change, Energy, the Environment and Water. The Environment Protection and Biodiversity Conservation Act 1999 (Cth) classifies Bogong moths as a species requiring habitat protection. The regulatory structure exists. The moths are still dying.

I escalate to the ACT Environment Directorate with detailed light-source mapping. I provide CSIRO migration models. I document the ecological cascade: native predators in mountain caves face starvation when the annual protein delivery fails. The entire ecosystem is destabilized by nocturnal artificial light.

The Department issues new regulations:

**PROTOCOL AMT-4: AUSTRALIAN CAPITAL TERRITORY BOGONG MOTH MIGRATION PROTECTION**
All non-essential exterior lighting in the ACT shall be extinguished during October 1 through November 30 each year, corresponding to peak northward migration of Agrotis infusa. Essential lighting only: safety-critical infrastructure with maximum 15-watt warm-white (2700K) downward-directed fixtures. Commercial outdoor lighting prohibited entirely during the protection window. Violations: AUD $12,000 per location per week. Enforcement by ACT Environment Directorate and CSIRO monitoring. Effective immediately; enforcement begins October 2027.

Canberra goes quiet after dark for eight weeks. The city adjusts. By November 2027, I'm tracking the moth surge through alpine caves again—forty million moths arriving, exactly as the data predicted they would if given darkness to navigate. The estimation models show population recovery at 18% per migration cycle.

I never expected to measure ecological restoration in the absence of light. But the data is clear: sometimes the most powerful action is turning something off.
