Does anyone know what these are?

Dp sent me this photo today, found in his workplace, does anyone have any idea what they are?

Grass seed?

Seeds on a tortilla?

Flour moths?

We need a closer photo and more information.

He works in biochem, pic is of whatever those things are on a filter paper

Still looks like grass seed to me. Where about in his biochem lab were they found?
