Rambur's Forktail

Fascinating facts about the Rambur's Forktail

• Rambur's forktail is the most widespread New World Ischnura, occurring from the United States down through Chile and extending to islands such as Hawaii and the Antilles. It is found in ponds, lakes, marshes and slow-moving streams where vegetation and sunlight are abundant, conditions that support its whole life cycle.
• Unlike most damselfly nymphs, which never inhabit salt water, the larvae of I. ramburii have been recorded in brackish environments and even in waters with sulphur content.
• The mating of this damselfly has been described as "enigmatic" because the male clamps the female's head with the terminal appendages of his abdomen while she draws sperm into her gonopore. John Edward Lloyd suggested that this wheel-like formation may have evolved to keep the female from escaping during copulation.
• Rambur's forktail hunts mosquitoes and a variety of other insects, catching them in flight over the water's surface. By feeding on these pests it naturally reduces their numbers in the ponds, lakes, marshes and slow streams it inhabits. The species is regarded as a beneficial insect because it supplies this pest-control service without any risk to people. Its presence therefore supports healthier freshwater habitats for both wildlife and humans.
• Male Rambur's forktails are easily recognised by their green bodies marked with blue on abdominal segments eight and nine. Female individuals show a wider palette, ranging from orange-red to olive-green, and some even match the male's colouration. These colour variations are typical of the species and help observers distinguish the sexes in the field. The vivid markings are displayed while the damselflies perch among vegetation near water.
