Yesterday in my dining room I found at least thirty to forty small white objects scattered on the carpet. The room has been cluttered with boxes recently and the curtains kept closed. Alerted by what looks like a slug trail, I cleared the boxes out of the way and found these small white things. They are about 1mm wide, 3mm long, very light and feel like fine tissue paper, indeed at first I thought they were screwed up bits of paper but they have liquid inside them. They seem to be completely smooth not segmented, but one or two had what looks like part of a head sticking out. At first because of the trail, I thought they might be immature silverfish, but they do not move (except for a slight wiggle) and seem unsegmented and without legs. They don't look like wooly bears (carpet beetles) either. It then struck me that they could be moth cocoons and I did see a small cream-coloured moth around this morning. Fortunately the caterpillars (which I have not seen at all) do not seem to have damaged the carpet. Are they moth cocoons and are they anythng to worry about? (I have vacuumed up nearly all of them, except for three specimens which I could bring round to the NHM as I am only next door.)
It's best to bring them in. The Identification and Advisory Service is located in the Darwin Centre. From the Main Hall follow the left side corridor (the Dinosaur Way) till the end. You will see a huge "Darwin Centre" sign above the stairs that go down to our level. Turn left after the stairs and ring the door bell.
See you later.
Moth (or other insect) pupae are the likely answer.
But I agree with Florin that somebody needs to see them.
A photo would be useful, if you could manage a good close-up. That could show details of wings, antennae, etc. (which you'd have difficulty seeing with the naked eye on such small specimens). That could help us decide which group the creatures belong to, eg. moths.
