Rainy summer boosts dragonflies across Kentucky, UK extension entomologist says

Kentucky residents noticing more mosquitoes and more dragonflies during late-summer showers may be seeing two parts of the same seasonal cycle, according to Jonathan Larson, an extension entomologist with the University of Kentucky. Larson said rainy weather that supports mosquito populations can also coincide with an increase in dragonflies, which prey on mosquitoes.

In an interview reported by WKYT, Larson said dragonflies are effective predators and that their presence can align with periods when mosquitoes are most active. He pointed to the relationship between wet conditions, aquatic insect life stages, and predator insects that hunt in the air.

WKYT reported that dragonflies have expanded across the state amid what the station described as a rainy summer and a mosquito surge. Larson’s comments focused on how dragonflies fit into Kentucky’s local ecology, noting that dragonflies hunt mosquitoes rather than being a nuisance themselves in the way some insects can be.

While mosquitoes are widely associated with bites and nighttime discomfort, the practical public-safety concern is increased exposure for people outdoors, including families with children and others using yards, parks, and outdoor common areas. Wet weather patterns that intensify mosquito activity can affect where and when mosquitoes are most noticeable.

Larson’s extension role involves translating insect behavior into understandable guidance for residents and communities. WKYT’s report tied his observations to the broader seasonal timing of insect populations, describing how increased rain can change insect numbers and the likelihood that predators are seen in greater concentrations.

The report also underscores that insect presence can fluctuate by location. Kentucky has many waterways, drainage patterns, and microclimates, and mosquito breeding conditions can vary block by block. In turn, where mosquitoes are more plentiful, dragonflies may also be more visible because food availability supports predator activity.

As late-summer weather continues to shift, residents who are bothered by mosquitoes may still face practical steps to reduce exposure. WKYT’s coverage centered on the natural predator dynamic, but it did not outline specific enforcement or public-health interventions in the segment.

For now, Larson’s message is that dragonflies can be a normal part of Kentucky’s response to rainy conditions, offering one natural check on mosquito numbers while residents watch for changing weather and insect activity across neighborhoods.
