Facts about Dragonflies
- 09
Over 5,000 species of dragonflies exist worldwide today, with approximately 2,000 species found in tropical regions where biodiversity and water availability are highest.
- 08
Most dragonfly species require specific water temperatures between 50 and 86 degrees Fahrenheit to successfully complete their aquatic nymph development and emerge as adults.
- 07
In warm climates, some dragonfly species complete their entire life cycle in just eight weeks, allowing multiple generations to emerge within a single summer season.
- 06
During their aquatic nymph phase, dragonflies are voracious predators that can consume up to hundreds of mosquito larvae weekly, making them valuable natural pest controllers in freshwater ecosystems.
- 05
The oxygen-rich atmosphere of the Carboniferous period allowed ancient dragonfly species to grow to wingspans exceeding 28 inches, nearly three times larger than modern dragonflies.
- 04
A dragonfly's immature nymphal stage can last up to five years in water before the adult emerges and lives only four to six weeks in air.
- 03
Dragonflies can reach speeds of 30 miles per hour and perform aerial maneuvers including hovering, flying backwards, and executing 90-degree turns mid-flight.
- 02
Fossil records reveal dragonflies inhabited Earth approximately 300 million years ago, making them among the oldest insect groups still in existence today.

With eyes containing 30,000 lenses each, dragonflies can see in nearly every direction simultaneously and detect movements as small as a single millimeter.
