Dragonflies Flourish Across Northeast Ohio Following Recent Rainfall

Recent rainy weather in Northeast Ohio has created ideal conditions for increased dragonfly activity throughout the region. These ancient insects become particularly active in the days following rainfall, when humidity levels remain high and their prey becomes more abundant.

Dragonflies are remarkable aerial predators that have inhabited Earth for over 300 million years, predating even dinosaurs. In Northeast Ohio, residents can observe approximately 164 species of dragonflies and damselflies, with many becoming more visible during warm, humid periods following rainfall.

“The rain creates temporary pools and enhances existing water bodies, which serves as both breeding habitat and hunting grounds for dragonflies,” explains Dr. Linda Orkin, entomologist at Cleveland Natural Science Center. “We typically see a surge in dragonfly populations about 24 to 48 hours after significant rainfall.”

These efficient hunters help control pest populations, particularly mosquitoes that breed in standing water left by rain. A single dragonfly can consume hundreds of mosquitoes daily, making them beneficial insects for our communities and outdoor spaces.

Dragonflies possess remarkable flying abilities that set them apart from other insects. They can hover like helicopters, fly backward, and reach speeds up to 35 mph. Despite their somewhat intimidating appearance, dragonflies are completely harmless to humans.

The life cycle of dragonflies is closely tied to water. They spend most of their lives—from several months to several years—as aquatic nymphs before emerging as the colorful adult fliers we recognize. The adult phase typically lasts just a few weeks to months, during which they mate and lay eggs to continue their lifecycle.

With the extended rainfall our region has experienced, conditions are particularly favorable for both dragonflies and their prey, creating excellent opportunities for nature enthusiasts to observe these fascinating insects in action.
