The present observation exhibits outcome of interactions between the chironomid larvae and members of two non-predator snail species and tadpoles that share the same space resource. In species ensembles of aquatic communities, the detritivores like midge larvae, tadpoles and snails exploit detritus as a resource. Movements of the snails and the tadpoles over larval abode cause the destruction of tubes. Rapid reconstruction of tubes is essential to avoid predation and development of midge larvae. The alteration in tube numbers and the decrease in tube length of midge larvae may be viewed as a...
