Criorhina differ from other bumblebee mimics - Mallota, Arctophila, Pocota and Brachypalpus by the form of their antennae: the first segments are thin and form a stalk, the third segment is shorter than it is wide.
In Criorhina, the face projects downwards, in contrast to Pocota and Brachypalpus.
The larva is figured by Hartley (1961) [13] and Rotheray (1993) [14] Adults are arboreal and found in most categories of both coniferous and deciduous forest with overmature trees and are seen visiting flowers to feed.
