Some characteristics of the trichoptera distribution in the Mesozoic of Eurasia (Insecta: Trichoptera)

The stratigraphic distribution and peculiarities of burial of caddis cases from 293 Mesozoic localities in Eurasia are analyzed. An attempt is made to analyze and interpret the co-occurrence of trichopteran cases and adults in the major localities. The main stages in the evolution of the building behavior of trichopteran larvae in the Mesozoic have been elucidated.
