Most solitary bees are non stinging insects. They reproduce in individual holes and quarries are worldwide known as their preferred habitat. In order to evaluate the ecological functions of the quarry of Fongba (Republic of Benin), we decide to study the solitary bees it hosts. The established bees and their habitat will be studied by means of hand cashing nets and nests screening at the sites and in a 200m buffer around the whole quarry area. The study of their metamorphosis will be done by establishing 20 sets of artificial nests at the quarry. The characterization of the bees will be done by morphometric methods targeted on the stereometric measurements of their parts and color under binocular microscope. This will help determine the bee species by comparison with the available specimens and by means of identification keys. The investigation artificial nests will be managed in cooperation with the administration of the quarry and the workers delegates to build up a live solitary bee bank. The bank will serve for deeper investigations on the solitary bees and will be valued through ecotourism and educational communications. This will also improve the awareness of the public and surrounding populations who will get more sustainable pollination services from the established solitary bee populations.
