Other species of seaweed flies include Coelopa nebularum and Coelopa pilipes. C. frigida feeds primarily on seaweed, and groups of C. frigida flies tend to populate near bodies of water. Climate change has led to an increase in C. frigida blooms along shores, which creates a pest problem for human beach-goers. C. frigida is also an important organism for the study of sexual selection, particularly female choice, which is influenced by genetics.

Criorhina berberina is a species of hoverfly. It is found in the Palaearctic from Fennoscandia South to Iberia and Italy. Ireland eastwards through Europe into Turkey and European Russia . C. berberina is a bumblebee mimic. The body has uniformly long dense pubescence, obscuring the ground-colour. There are two forms one with the pubescence more or less extensively blackish, one in which it is entirely yellow or tawny. 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.
