“…A similar analysis, reported by Butakka et al (2016) [ 7 ], could categorize the food content as algae, fungal spores, and plant fragments but there was inadequacy in diverse composition and high-taxonomic resolution. Certain observations could identify phytoplankton [ 5 , 8 ], mostly algae [ 9 , 10 ] and detritus [ 11 , 12 ], as the major gut content in the chironomid. However, these results could not profile detailed taxonomic specificity and diversity of food sources.…”

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

“…The other factor on the chironomids feeding is swallowing food non-selectively and selectively in accordance with food availability, type, and size (Armatige et al 1995). Studies of chironomid feeding show that the diet of chironomids constitutes of detritus and associated microorganisms, macrophytes, invertebrates, and especially algae (Baker and Mclachlan 1979;Armitage et al 1995;Sanseverino and Nessimian 2008;Butakka et al 2016;Öterler et al 2018;Kornijo´w et al 2019).…”

The roles of larval chironomids in the food chain of both the lotic and the lentic ecosystems are very important. On the one hand, chironomid larvae feeding on algae, diatoms, rotting organic matter, plant, and animal residues also play an important role in these systems as a source of food for other carnivores and omnivorous organisms. In this study, the gut contents of Cryptochironomus defectus (Kieffer, 1913), Cladotanytarsus mancus (Walker, 1856), Polypedilum scalaenum (Schrank, 1803), Tanypus kraatzi (Kieffer, 1912) collected from the freshwater ecosystems located in the northern parts of the Thrace region of Turkey were analyzed to compare their feeding habits. As a result of the analysis, it was determined that while plant fragments were dominant in C. defectus species in the gut content (44.3%), algae were dominant for C. mancus (44.7%), P. scalaenum (63.5%), T. kraatzi (65%). According to the results of the Shannon-Wiener (H') index species, diversity of the P. scalaenum was found to be the highest among the larvae (H'= 1.345). Also, according to the Bray-Curtis similarity index, the most similar types of gut contents were P. scalaenum and C. defectus (38%). This low rate indicated that the species have different food preferences.
