Today I want to share FIVE FUN FACTS about dragonflies 🙂 A beautiful Common darter lady (Sympetrum striolatum) kindly agreed to demonstrate the facts in my pictures!
★ FACT 1: They were the first insects to inhabit this planet – 300 million years ago! In other words: they’ve had a looong time to perfect the art of flying and hunting.
★ FACT 2: They’re flat out terrifying if you’re a mosquito or other kind small bug, because they don’t simply chase down their prey but they snag them from the air with a calculated aerial ambush! Dragonflies can judge the speed and trajectory of a prey target, and they’re so skilled they have an impressive 95% success rate when hunting.
★ FACT3: They can fly in any direction, including sideways and backwards! (How cool is that!) Plus, they can hover in a single spot for a minute or more. But that’s not all. They’re also fast – some species reach almost 30 km/h (18 mph) – and one species (Globe skimmer) flies almost 18,000 km (11,000 miles) during migration which is the world’s longest insect migration. (Compare this with the famous Monarch butterfly migration of 2,500 miles.)
★ FACT 4: Both dragonflies and damselflies are in the order Odonata, which means “the toothed ones”. When hunting, they can catch the prey with their feet, tear off its wings with their sharp jaws (so the prey can’t escape) and scarf it down – all without needing to land. In short: Their ability to rip apart their prey takes their predatory prowess to another level.
Update: It should be noted that dragonflies don’t bite humans and they don’t have any stinger! i.e. they cause no harm to humans. (Thanks for pointing this out, Greta)
★ They have nearly 360 degrees vision! The enormous compound eyes contain 30,000 facets and they can see the world in colors we can’t even imagine. (In depth read here)
Update: It’s also worth mentioning that dragonflies have a significant, positive ecological impact. In its nymph stage, they eat harmful aquatic organisms and thus help keep our waters clean. The nymph can contribute to the ecosystem for up to five years before becoming a mature adult! As adults, they mainly help humans by eating mosquitoes and other insects that spread diseases such as malaria, yellow fever, anthrax, etc.
