Molecular Ecology, Volume 35, Issue 1, January 2026.ABSTRACT Aquatic insects are the most biodiverse freshwater animals. DNA metabarcoding data are increasingly used to assess variation in insect communities, but they are rarely integrated with information on the abundance or biomass of different taxa that can provide key insights into their functional responses.
