After that they swim to the surface of the water where they emerge from the water and fly off. When the tadpoles first hatch, a quantity of fresh pond weed at this stage is very important; partly as food and partly as support for young tadpoles. When Valdez surveyed ponds in a half-acre area, he found that 80 percent of the tadpoles he observed were living in ponds free of diving beetles, suggesting the beetles might be influencing tadpole survival (Aust J Zool, doi:10.1071/ZO19039, 2019). The water flow brings food particles into the net, which get captured and are eaten.

When at rest the wings look like a little tent over its back. On the other hand, larger species ingest small snakes, lizards and rodents. Some larvae, however, do not freeze when the water surrounding them does; others overwinter eggs inside the gelatinous matrix, which provides protection. These houses are so specialized, that you can almost always identify a caddisfly larva to genus if you can see its case.
