We analyzed the dietary composition of Polypedilum larvae among two contrasting habitats (river and weir). Our approach was (i) to apply eDNA-based sampling reveal gut content chironomid larvae, (ii) diversity contents in aquatic habitats, (iii) assessment habitat sediment condition with food sources gut. The most abundant Chlorophyta river (20%) weir (39%) chironomids. average ratio fungi, protozoa, zooplankton chironomids 5.9%, 7.2%, 3.8%, while it found decreased 1.2%, 2.5%, 0.1% Aerobic fungi midge guts were 3.6% 10.34% SC IS, they range 0.34–2.58% midges. hierarchical clustering analysis showed a relationship environmental factors contents. Abiotic (e.g., pH) correlated clustered pattern phytoplankton minor groups fungi. This study could help understand source conditions by using eDNA metabarcoding as an effective tool determine composition.
