Revised chronology of Trichoptera evolution

Abstract

Based on a recalibrated BEAST diversification time analysis, we provide a revised chronology for the evolution of major lineages of Trichoptera. Fossil evidence indicates that caddisflies evolved at least by the Norian of Late Triassic (median age 222.6 Ma), compared with our estimate of at least 201.3 Ma. The ancestors of suborders Annulipalpia and Integripalpia also evolved as early as the Norian. Fossil evidence indicates that the ancestor of subterorder Phryganides lived at least by the Aalenian of Middle Jurassic (median age 173.6 Ma), compared with our estimate of at least 174.1 Ma.
