Loft Visitor

These fragile structures, 25 and 45mm diameter, hung bell-like on fine threads from the joints in the felt between my rafters. In the smaller one there is a spherical cell-like structure, reminiscent of a honeycomb. A similar structure in the larger one is loose in the concentric spherical bowls, which haven’t opened up so much. They looked whiter in the loft a couple of days ago. They were solitary, one between each pair of rafters. Although there is mould on the rafters, there was no musty or damp smell in the loft, which seemed dry.
Are they animal or vegetable?.

wasp nest

I am sorry I cannot identify the species [not my knowledge area] but I am impressed with your description and attention to detail, particularly the broader environment of location. So many i-Spotters just post a picture with no description. Yet this is often crucial to identification.
Please continue with this level of observation.

If you re-classify -

As an invertebrate, more people interested in that group may see this, and might - just perhaps - be able to be more specific.

Wasp Nest

Thanks everyone.
Now I know what to look for, they are tiny versions of a number of nests shown on the web. (The smaller one has only a dozen cells in the comb.)
They appear dead. There are several others. Are they a menace; should I move them outdoors, would you say?

Made by Queen Social Wasp

These structures are made by a queen social wasp after overwintering. The queen will make a few cells and lay eggs for a few larvae which will then develop into workers and help with the nest construction. Soon the queen will just be egg laying and the offspring workers constructing and maintaining the nest.

The fact that these structures have not become bigger indicates the queen may have died. I don't know if a queen will start another nest if one fails.

They will often be constructed in a loft, shed, garage etc where it will be dry.

You cannot move them outside, because you very likely could not find the same habitat as the queen has chosen, the queen will not be able to find it, and you will not be able to attach it!
