Alien mantids in a tropical paradise: First record of the giant mantis Sphodromantis viridis (Insecta, Mantodea) for the Canary Islands (Spain)

Abstract

The presence of adults, nymphs, and oothecae of the African giant mantis Sphodromantis viridis Forsskål is for the first time recorded on the island of Tenerife, the largest and most populated of the Canary archipelago, an autonomous Spanish community in the Atlantic Ocean. The discovery took place in a popular water park rich in non-native plants in the municipality of Costa Adeje. It is possible that anthropogenic movements, particularly the massive movement of tourists and goods that continually cross this small archipelago, aided the dispersal to the area of this mantis, which for some years has also been expanding in many areas of the Mediterranean basin. A hypothesis on the ecological impact and the possible invasiveness of this extremely adaptable species is discussed and supported by the large number of sightings of oothecae and specimens that are, fortunately, still confined within the west coast of the island.
