Fellow Beeks,
What is the preferred insulation for the roof space in a top bar hive, is it necessary and also should I insulate the side spaces, the hive is contained in the mid 1/3 of the Hive

Yes, you should insulate the space all year round. Use anything you have handy: wool, straw, glass fibre (loose material should be in a bag), old pillow, newspaper, etc. No harm in adding extra in the spaces beyond the followers. No such thing as too much insulation!

Any merit in simply building in a rigid-foam insulation system, contained (naturally) by wood, etc.? That has some appeal to me for reasons I can't yet explain.

I have a small top bar hive, 21 bars, about 36" long. There were combs on all the bars so I left them all in for the winter. I put 3/4" pink foam insulation on the bottom. Then I wrapped all the sides in 1 1/2" pink foam insulation. I taped all the joints with gorilla tape, similar to duct tape. I left an opening of 1/2" ht and 3" long for the entry. I have a flat top on the hive. I built a top to go over the existing top. It had 3/4" pink foam insulation on the sides and under its plywood top. I extended this top to cover the landing board. 1st winter for the bees and no supplimental feeding and they survived the winter. This spring I got 3 qts. of honey off of the last 3 bars. I'm going to build my next hive to include 3/4" foam insulation within dbl. walls and the floor. The roof is still a question but will be a gable roof, with a ridge vent. I'm thinking of some sort of a warre quilt over the top bars but still allowing airflow to remove excess humidity.

Yes to the Warre quilt. Sealed insulation just keeps the moisture in but a quilt allows it to slowly get out while adding insulation. A simple version is an old pillow as has already been mentioned or several layers of hessian over flywire.

Cheers

Conserving wild bees

Research suggests that bumble bee boxes have a very low success rate in actually attracting bees into them. We find that if you create an environment where first of all you can attract mice inside, such as a pile of stones, a drystone wall, paving slabs with intentionally made cavities underneath, this will increase the success rate.

Most bumble bee species need a dry space about the size a football, with a narrow entrance tunnel approximately 2cm in diameter and 20 cm long. Most species nest underground along the base of a linear feature such as a hedge or wall. Sites need to be sheltered and out of direct sunlight.

There is a spectacular display of wild bee hotels here
