The “Pollinator Information Network for Two-Winged Insects” (PINDIP) addresses the role of Diptera in plant-pollination in the Afrotropical Region. It does so, by creating a network for Diptera taxonomists and plant-insect interaction ecologists. For instance, several important Afrotropical institutes currently do not have Diptera curators and technical staff and require guidance in terms of sorting and curating material. We organize training courses that focus on tutoring collection curators, technicians and students, in order to build a sustainable network of trained taxonomists on Afrotropical Diptera within the Afrotropics.
