Chaoborus are distant cousins to chironomids. They are one of if not the most challenging food sources to match as the larva and pupa are typically transparent.
Chaoborus pupa can be a subtle apple green color featuring a dark thorax and no white gills. They are very active and move through the water with a spring-like action. Their active swimming action, small size (typically size 14 or less), and lack of white gills are key features to look for.
