Callicera is a Holarctic genus of hoverflies [1]
They are beautiful metallic flies, with strikingly long antennae are medium-sized to rather large (wing length 9·75–15 mm.) bumblebee mimics. All the species are considered rare. Callicera larvae live in the moist rot-holes of overmature trees as saprophages. [2] [3] [4] [5] [6] [7] [8] Callicera have been used as bioindicators.
