Viburnum tinus is among stars of the Mediterranean spring. Its dark green leaves contrast fragrant pentamerous flowers in white or pale pink, evolving into dark blue fruit resembling small pearls. Yet this obvious picture from maquis has its invisible side .It is called domatium, after Latin word domus, for home. Domatia are microscopically small chambers at the under sides of the evergreen leaves. Plant grows domatia to host mites. In this way Viburnum tinus can be seen as a botanical skyscraper with many tiny apartments for arthropod neighbors. Imagine a little mite calling her friends to come over for a party at her condo! I am kidding, it only fascinates me to recognize there is another life underlying the botanical beauty of the plant we can see with our eyes. It is like a parallel world. Only the question remains, are the mites, or are we , at the right side?
