Bronze Flies at UK Garden Pond: Dragonflies!

Question: UK pond. 1-cm bronze shiny flies with clear wings, black wing tips. Swarmed after filter cleaning. Not a problem—just curious.

Answer: Dragonflies (Order Odonata)

• Large multifaceted eyes, two pairs transparent wings, elongated body
• 34 species in UK (see British Dragonfly Society)

Beneficial Predators

• Eat mosquitoes, midges, flies, bees, butterflies
• Larvae (nymphs) are aquatic—pond = breeding habitat
• Do not bite or sting humans

Why They Swarmed

Filter cleaning disturbed nymphs/emerging adults. They're attracted to water features. Celebrate them—they're free mosquito control!
