Blue-Tailed Damselfly

Fascinating facts about the Blue-Tailed Damselfly

• A blue-tailed damselfly's eyes wrap 300 degrees around its head — nearly complete vision except for a blind spot directly behind. This 360-degree sight means it can spot a mosquito the size of a pinhead moving in any direction while it hovers motionless, giving it a hunting success rate that puts most predators to shame.
• Female blue-tailed damselflies come in three different colour morphs — some blue like males, others orange or green — and this isn't random variation. The colour you see determines which males will chase her, which males she'll reject, and ultimately how many offspring she'll have. Evolution has locked mating preference into pigment.
• A blue-tailed damselfly's life cycle begins and ends in water, but the underwater larval stage lasts 2–3 years while the flying adult phase lasts only 4–6 weeks. That means 99% of its existence is spent as a nymph hunting other aquatic insects in the dark, crawling across pond plants with raptorial front legs that fold like a praying mantis.
• When a male blue-tailed damselfly finds a female, he doesn't let go — literally. They mate while tangled together in a wheel shape, sometimes staying locked for 30 minutes or more. Even after she dives underwater to lay eggs, some males cling to her, ensuring no rival can mate with her before she returns to the surface.
• Blue-tailed damselflies have been spreading north across Europe for the past 50 years, shifting their range by over 1,000 kilometres as temperatures warm. They're now found in Sweden and Scotland where they didn't exist a generation ago, making them one of the fastest-expanding insects on the continent — a living record of climate change written in blue wings.
