The larvae are aquatic, but there must be enough solid food for the larva to complete development. This is why they are found in water with high levels of organic matter. The siphon on the back of the larvae remains at the surface of the water while the larva moves throughout the water. This allows for the larva to search for food without having to go to the surface to breathe. It was reported that the larvae reproduce by neoteny or paedogenesis, where the larva copies itself. There has only been one observation of this happening.
