About the Large Red Damselfly
The large red damselfly (Pyrrhosoma nymphula) is a species of damselflies belonging to the family Coenagrionidae. It is native to the western Palearctic. This species is a mainly European damselfly, with some populations in Northern Africa and Western Asia.
These damselflies inhabit small ponds, lakes and dikes, and occasionally slow-moving rivers. They tend to avoid fast flowing water. Pyrrhosoma nymphula can reach a body length of 33–36 millimetres (1.3–1.4 in). These large and robust damselflies show black legs and wing spots in both sexes.
Mature males have red eyes and a black thorax with red shoulder stripes in mature specimen, but yellow stripes in immature. In fact ante-humeral stripes change to red with age. Abdomen is red with black small rings and bronze-black bands towards the apex (segments 7-9). Wings are hyaline, with a blackish pterostigma. Mature females occur in three colour forms (typical, fulvipes and melanotum), from mostly black to mostly red, but all have yellow bands around the abdominal segments. Some intermediate forms also exist.
The form typica has more black on its abdominal segments than the form fulvipes... Wikipedia →
