Large Red Damselfly Pyrrhosoma nymphula
The first damselfly to emerge in Spring and as the name suggests are mainly red-bodied.
The male has a deep red abdomen with bronze and black bands, while the female (which has three colour forms) has more black on the abdominal segments in all colour forms. However, in all cases this is the only 'red' damselfy commonly encountered in the UK.
Temperature allowing, begins to appear towards the end of April and onwards into August.
*The Small Red Damselfly Ceriagrion tenellum is found at one site in Norfolk (Scarning Fen near Dereham) but is mainly a damselfly of boggy heaths in some southern counties.
