"Hotel de Charme"

In the Jardin des Plantes - the largest botanical garden in France - there is an impressive insect hotel called 'Hotel de Charme'.  With urbanization diminishing the insects which play such an important role for the pollination of both cultured and wild plants, these 'hotels' are built more and more.  They can be very decorative and are certainly useful in urban landscapes where insects are on the wane.

This smaller version we found on the roof garden of a hotel (for people) where a roof garden with wild flowers is planted.  Soon flowers will attract insects and now is perhaps the right time to plan building your very own insect hotel.  We know that the snow is piling up in Boston, but eventually it will melt and the insects have to have a place to stay.
