Unusual swarms of dragonflies are being reported across California, with people spotting large numbers of the insects in parks and around farms. Multiple reports describe dragonflies flying in clusters, including near ponds where they may hunt mosquitoes and other small insects.
Experts cited across the coverage say the timing and conditions likely play a key role. They point to unusually warm spring rains that can boost insect activity and increase food availability in freshwater and agricultural areas, helping dragonfly populations surge or become more noticeable. Both outlets frame the event as a seasonal, weather-related phenomenon rather than a sign of an unusual threat.
While the reports focus on different locations and behaviors—such as swarming in public spaces versus activity around farmland and standing water—they converge on the same explanation: recent warm, wet weather increases the likelihood that dragonflies appear in conspicuous numbers.
