Pupae or seed?

Pupae or seed?

I keep finding these unusual disc shaped brown objects floating in the pond at the moment. They look a little like salami slices.
I had assumed they were seeds, fallen into the pond. However, yesterday I squeezed one and the contents that sprayed out was yellow and milky, not thick like I would expected from a seed. I wondered whether this could be a pupae (that I had inadvertantly destroyed!).
The pond in which I find these is well-established, and supports good populations of a number of water beetles, and six caddisfly species too.

    Likely ID

Yellow flag seeds

Are there any yellow flag/flag iris plants at the pond? You mystery objects look like the seeds of that plant that have fallen from the ripe pods which split open to drop the seeds inside.
