Pupal cases? - Coleophora serratella

Pupal cases? - Coleophora serratella
South Frontenac, Frontenac, Ontario, Canada
Size: 1 cm
I found dozens of these affixed to the terminal twigs of a White (Paper) Birch overhanging a small lake. It looked like there were perhaps two types, cocoons and eggs? Long cigar-shaped papery things, and then shorter hard-looking claw-shaped things. They occurred singly or in groups of two or more.

Moved
Moved from Casebearer Moths.
I believe these are all Coleophora serratella. This is the only species known to make a tubular (as opposed to spatulate) leaf case on birch, and when younger it makes a strongly curved, composite leaf case.

Casebearers
These are the cases of casebearer moth larvae (Coleophoridae). There are hundreds of species, and host plant can be helpful, but I think there are several similar ones on birch.

 
Thanks!
I was thinking they were probably a little moth cocoon, but didn't really have an idea on which. Certainly were lots of them! Thanks for the ID!
