Von: Diehl Johanna Gesendet: Donnerstag, 29. Juni 2017 12:24 An: pestlist@museumpests.net Cc: herbert.reitschu...@khm.at Betreff: AW: [pestlist] Please help me with ID of insect Dear all, I have open the frame and have now microscope images of the insects. I am quite sure, that Tony and Louis were right that these insects are thrips (Thysanoptera). Because I found something that could be feeding tracks (see second picture) I am not sure what to do. I would clean the frame, the aquarelle and the passe-partout. Should I also treat the object with nitrogen? What would you recommend??

If possible, get a close-up image of the critter. It will also help if you can give us an idea of the scale? Measure it if possible. Sorry that I cannot be of more help at this point.

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.

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.

Please try to find a way to obtain better images. Alternatively, sample the physical material and consider submitting it for evaluation. Best regards, Rich Richard Pollack, PhD.<mailto
