Pyrrhosoma nymphula Coenagrionidae Large Red Damselfly

Biology male female Irish distribution

Pyrrhosoma nymphula

Widespread and common. Adult flight period extends from late April to August. The only red species of damselfly in Ireland. Pyrrhosoma nymphula is the earliest Odonata species on the wing, appearing in warm Springs in late April. It is found in most habitats except for the most exposed sites. It has a preference for small acidic pools and is able to persist on many very dry sites that have become unsuitable for other Odonata. It is also quick to colonise newly created ponds.

The only other red damselfly in the British Isles is the Small Red Damselfly Ceriagrion tenellum, however this species does not occur in Ireland.
