I am intrigued by the question of whether or not bees recycle (or reuse) wax. I live in suburban Melbourne, Australia, and have had bees for just one year now. I had seen a TV documentary film, “The Great Australian Bee Challenge” which provided the incentive and impetus for me to study everything I could find on the subject of beekeeping. (This documentary consists of two episodes – each one about an hour long – and can still be viewed on Youtube. Just do a Google search for “The Great Australian Bee Challenge”).
There have been lots of comments made by beekeepers, about how “expensive” it is for bees to make new wax – about how much honey they must consume to produce a given amount of wax. I would certainly like to know if any definitive studies have been done to determine accurately the answer to this question. It seems to me that there would be significant benefit to both the bees and their keepers, if ways could be found to actively encourage bees to reuse wax which had previously been harvested or salvaged by beekeepers.
All of the answers I have heard (from beekeepers whom I have asked) have tended to be negative.
I made an interesting discovery a few months ago, in our Autumn, of a significant amount of empty comb freshly built upwards from the bottom of a new base which had been in use in a hive for only three months. There was enough of this new comb to fill a couple of coffee mugs, and it was very dark in colour, almost like the colour of dark chocolate. I asked around what this might be, and one beekeeper suggested that it was propolis – and this seems to me to be likely correct.
I like the idea expressed by another writer to this forum, about giving the bees some coloured wax. I wonder whether red or blue food colouring could be added to some melted wax? Or some other kind of colouring? In what form should such coloured wax be given to the bees? Foundation sheets? I am inclined to do some experimenting of my own in the next few weeks with Spring just around the corner here in Australia. I shall look with interest at any suggestions that other people may have.
