Sydney moth swarms will linger in waves for weeks

Bogong moths will remain for several weeks longer, arriving in waves as different groups migrate south.

Sydney's bogong moth invasion is far from over. Thousands of endangered bogong moths are moving south toward the Alps.

Experts expect them to stay for weeks, arriving in rolling waves rather than all at once. Wind and weather decide when each group moves on.

Heat may push them further, but no one has studied what starts their migration, so exact timing is unclear. Some moths tucked in dark corners could stay even longer.
