- I have been keeping these caddisfly larvae in an aquarium on the back porch.
- I hope to raise them to adults which are easier to identify to species.
- During a cold snap a layer of ice formed on the water surface in the aquarium.
- At night I noticed that the caddisfly larvae would crawl about on the undersurface of the ice.
- They appeared to be feeding.
- What could they be eating on the undersurface of the ice?
- Think about the debris that floats up from a stream or lake bottom and gets trapped under the ice.
- They have been identified as belonging to the genus Lenarchus.
- According to the literature these larvae feed on organic sediments.
