Notes on the distribution and biology of the Splendid Cruiser - Macromia splendens (Pictet, 1843) - in northern Portugal (Odonata: Macromididae)

Macromia splendens (Pictet, 1843), is considered by many odonatologists among rarest and most threatened European dragonflies. During the last few years, the authors have carried out field work to detect this species in continental Portugal, from the northern border to the river Mondego: the results are presented here.
