The genome of a retreat-making caddisfly

The caddisfly Stenopsyche tienmushanensis Hwang was among the first described trichopterans by Chinese researchers. Sixty years after its scientific discovery to humans, the genome sequence of the species is now described for the first time, representing the best caddisfly genome by far. The new genome reveals potential linkage between genomic features (e.g., expansions of P450 and OBP families) and freshwater adaptations (e.g., tolerance to water pollutant, efficient mate finding during adult life stage). An exciting discovery of the new genome is the first description of the full-length H-fibroin gene, which codes for the major protein component of the caddisfly silk, a key adaptation trai
