Larval case of unidentified dragonfly

Observation - Larval case of unidentified dragonfly. Description: A dried larval case of an unidentified dragonfly, approx 4.5 cm long, found in my pond. I have sometimes accidentally caught these in the net when clearing algae, and they are very strong in your hand! Does anyone know it's species?
