The Bees and Wasps (Hymenoptera Aculeata) of the Balearic Islands, their contribution to environmental and economic well-being and to scientific research

[eng] To complement a recent publication on the aculeate Hymenoptera (bees and wasps) biodiversity of the Balearic Islands, this paper focuses on the wider ecological role played by this group within the Balearics. Current knowledge is placed in its wider geographical context, with special emphasis on Mediterranean islands. The paper draws attention to the essential role of bees and wasps within the ecosystem, their value, threats and conservation needs, including sites, biotopes and endemisms. Illustrations are provided to demonstrate the diversity and attractiveness of the many bees and wasps across the Islands.
