Dear all, thank you for your help. I will open the frame next week and will make better pictures.

These insects regularly squeeze themselves into picture frames (they have evolved to insert themselves into very narrow spaces in the plants on which they feed). They will do no damage themselves, but occasionally a dead thrips can act as a focal point for mould, which may damage works on paper, so they are best removed from the frames.

If a standard microscope is not readily available, a simple microscope attachment for the smartphone can be obtained for a very reasonable price. https://www.amazon.com/dp/B00QLYPMZW?psc=1 Good luck!

Have you any ideas? The insects move, that means they are alive and they are very small (2mm). But we will open the pictureframe anyway to get a further view on the problem.

Could they be silverfishes? Please help me with the ID… Thank you very much! Johanna Kunsthistorisches Museum Wien Mag.
