Forest dragonfly encounters desert dragonfly: Aeshna cyanea syntopic with Orthetrum ransonnetii on Fuerteventura, Canary Islands (Odonata: Aeshnidae)

Aeshna cyanea is a new addition to the fauna of Fuerteventura, Canary Islands. In this study the circumstances surrounding the discovery of an emerging female, with exuvia collected, in a permanent pool in arid environment, in the Barranco de Rio Cabras, are described. The breeding record, syntopy with typical desert species (e.g., Orthetrum ransonnetii) and potential explanations for this unusual occurrence are discussed.
