(subtitle) data on wild bees, hoverflies and butterflies (abstract) This dataset was produced in the framework of the work package 1 (task 2) of the Horizon EU project Safeguard. The dataset encompassess trait data for three groups of pollinators: wild bees, hoverflies and butterflies, as well as phylogenetic data extracted from the GenBank. Information on traits comes from different literature sources, as well as direct measurements in collections and published databases. Some of the traits are common accross different species groups, while some traits are unique for particular group. (method) Litherature search and direct measurments on specimens. (dataset) This dataset compiles trait data for European wild bee, hoveverfly and butterfly species, and includes different categorical or numerical values for particular traits. It also contains phylogenetic information for species.
