Warm, wet spring weather has driven a surge in fly populations across New South Wales, with the insects swarming beachgoers, hitching rides on pedestrians, and seeking moisture from people's eyes and mouths. The influx has left many Sydneysiders wondering whether the city is experiencing an unusually severe fly season.
Experts attribute the boom to ideal breeding conditions created by recent rainfall and higher temperatures. Flies that typically remain in bushland have migrated into urban areas in search of food and moisture, drawn by the electrolytes in human saliva and tears.
While the phenomenon has caused widespread annoyance, entomologists note that such outbreaks are not unprecedented. The current numbers may simply be more noticeable after a period of lower activity, amplifying public perception of a 'plague'.
