Adults in the subgenus/genus Geranomyia are characterized by elongate mouthparts used for taking nectar from flowers. They display an up-and-down bobbing motion on the surface of rocks or leaves. This bobbing is especially noticeable immediately after the fly has landed or when it has been disturbed.
Food
The larvae feed mainly on algae.
Life Cycle
The larvae spend their lives in gelatinous tubes constructed on rocks covered with algal growth, where the surface is constantly wet along streams or vertical cliffs.
