Moth man scales six peaks as bogongs return in force

Key points

• Researcher Connor Marsland has scaled six peaks in the Brindabella Range to monitor a surge in bogong moths. The annual migration, which has been unusually visible this spring, saw thousands of moths coat walls and windows across NSW.
• Marsland, a PhD student at Western Sydney University, is studying the moths' migratory flyways and behaviour at aestivation sites.
• The boom in numbers is encouraging, but researchers caution against interpreting it as proof the species' future is secure.
