Bogong clouds over Manly heath

Where there is still coastal bush and heath left in Manly today there were huge clouds of bogong moths (Agrotis infusa). Flying at dusk in high winds in a very directed way, tanking up especially on the flowers of the coastal tea-tree (Leptospermum laevigatum). Their migration path of some 1000 km each year has been going on forever. Before they contained arsenic they made good tucker.
