About Dragonflies and Damselflies: the wider group
Order-level background for Odonata, the group containing Leucorrhinia patricia. Species-specific details appear above.
Group overview
Odonata includes ~6,000 described species of dragonflies and damselflies. Dragonflies are among the fastest flying insects, reaching 36 mph (58 km/h). They can fly in any direction including backward, and hover in place - each wing operates independently.
Ecological role of the group
Dragonflies predate dinosaurs by nearly 100 million years - fossils date to 325 million years ago. The largest dragonfly ancestor, Meganeuropsis permiana (285 mya), had a 75cm wingspan, enabled by atmospheric oxygen levels of 31-35% compared to today's 21%. Dragonflies have a 95% hunting success rate - the highest of any predator.
Economic and practical significance of the group
Dragonflies are voracious predators that consume hundreds of mosquitoes daily, providing natural pest control worth millions in reduced mosquito-borne disease risk. A single dragonfly can eat 30 to hundreds of mosquitoes per day.
