Abstract

Caddisfly adults and cases were relatively common fossils from the Mesozoic but the pupa is extremely rare. Here we described two well-preserved and uncased caddisfly pupae from the locality near the Shanghujia Village, Shouchang Township, Jiande City, Zhejiang Province, East China. New material including two pupal fossils with rather good detailed structures preserved such as mandible, abdominal hook plates, and anal processes. The new material provides new evidence for understanding development stage of Mesozoic trichopterans.
