Keeled Skimmer

Orthetrum Coerulescens

Orthetrum Coerulescens

Info

Often called the Keeled Skimmer, this agile aviator is a specialist of the wetlands and heathlands. With its dusty-blue abdomen and striking yellow wing-spots, it looks like a tiny piece of the summer sky has fallen to patrol the water’s edge. While many dragonflies are restless, the Keeled Skimmer is a "percher," often returning to the same sun-baked stone or twig after every hunting flight.

πŸ” How to Identify

  • πŸ’Ž The Blue Bloom: Mature males develop a pale, powder-blue "pruinescence" over their bodies, which looks like a fine dusting of flour or wax against their dark faces.
  • πŸ‹ Golden Wing Spots: Look closely at the tips of the wings; they possess elongated, yellow or pale orange pterostigma (wing spots) that help stabilize their flight and signal to mates.
  • πŸ“ The Keeled Ridge: Its namesake feature is a small, raised ridge (a keel) on the second segment of the abdomen. Females and immatures are a contrasting golden-brown with a distinct black line running down their back.

🌲 Habitat & Ecology

  • πŸ¦‹ The Aerial Assassin: These are "friendly" insects for humans but nightmares for pests. They are top-tier predators, devouring gnats, mosquitoes, and flies mid-air to help keep local insect populations in balance.
  • πŸ’§ Acidic Aspirations: You will most likely find them near slow-moving, shallow water. They are specialists of peat bogs, heathland seeps, and acidic streams where other dragonfly species might struggle to thrive.

⚠️ Safety & Toxicity

  • πŸ›‘οΈ Friendly Status: The Keeled Skimmer is completely harmless to humans and pets. They do not have a stinger, and they do not carry diseases.
  • 🀏 Gentle Giants: While they have mandibles for eating smaller bugs, they are not aggressive toward people. If handled very roughly, they might attempt a tiny "nip," but it is rarely strong enough to break the skin.

✨ Fun Fact

The blue "dust" on the male isn't actually his skin color; it is a specialized wax produced by his body. This waxy coating helps reflect UV light, preventing the dragonfly from overheating and protecting his internal organs from the sun while he perches in open, exposed areas!
