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.

Pioneer

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.

Hunter

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.)

Wings

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)

Jaws

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)

Eyes

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.

First week of October, but I still found some small bugs to photograph- A crane fly, a dragonfly, a butterfly 🙂

coupling

Yesterday I went back to the ‘damselfly-mating-tree’, but it was empty. But further down the canal there was another tree, and it was full of damselflies! While I was studying them, a dragonfly couple came flying in tandem. Next to the damselflies they looked massive. I tried to get a shot but they chose a branch of the tree on the other side (over the water) so I couldn’t get close. Luckily, they eventually moved to the grass (yes! on the “right” side of the canal, I’m so lucky!) and I could take a picture of them. They are Ruddy Darter dragonflies, in Dutch they’re called “Bloedrode heidelibel” but only the male is blood-red and the female more yellowish.

finally

Today, for the first time the whole summer, I finally spotted a dragonfly! A male Ruddy Darter who posed for several minutes on the grass. To say I was happy is a huge understatement, I was so thrilled I could barely hold my camera still!
