Large Red Damselfly
Pyrrhosoma nymphula
This record describes Pyrrhosoma nymphula (species). Recorded family: Coenagrionidae. Recorded order: Odonata.
Identification and Appearance

Often the earliest dragonfly or damselfly to appear, it is relatively easy to identify being red and black, with the black legs, which distinguish it from the Small Red Damselfly. Larvae are distinctive with extended wing sheaths, which reach almost to abdominal section 6. The head is squarish, with a straight line forming its rear margin. Two dark bands are present on the femur. Broad, strongly pointed lamellae with characteristic dark spotting. The Large Red Damselfly has a preference for well-vegetated sites, and is found on a variety of water bodies including ponds, lakes, rivers and canals. The Large Red normally has a two year life cycle. Unusually for dragonflies, the larvae are territorial as well as the adult males. This species is widely distributed though somewhat local within the VC55 area. This species is widely distributed though somewhat local within VC55. The Large Red Damselfly has a preference for well-vegetated sites, and is found on a variety of water bodies including ponds, lakes, rivers and canals. The Charnwood area would appear to be a stronghold, though records have been received from scattered locations throughout VC 55 (Grover and Ikin, 1994). Historically it has been described as 'widely distributed' (Gillman, 1936) and 'abundant' (Longfield, 1949), though it seems unlikely that it was ever more widely distributed than it is at present.

About Dragonflies and Damselflies: the wider group
Order-level background for Odonata, the group containing Pyrrhosoma nymphula. Species-specific details appear above.
Group overview
Odonata includes ~6,000 described species of dragonflies and damselflies. Dragonflies are among the fastest flying insects, reaching 36 mph (58 km/h). They can fly in any direction including backward, and hover in place - each wing operates independently.
Ecological role of the group
Dragonflies predate dinosaurs by nearly 100 million years - fossils date to 325 million years ago. The largest dragonfly ancestor, Meganeuropsis permiana (285 mya), had a 75cm wingspan, enabled by atmospheric oxygen levels of 31-35% compared to today's 21%. Dragonflies have a 95% hunting success rate - the highest of any predator.
Economic and practical significance of the group
Dragonflies are voracious predators that consume hundreds of mosquitoes daily, providing natural pest control worth millions in reduced mosquito-borne disease risk. A single dragonfly can eat 30 to hundreds of mosquitoes per day.
