Waxing Eloquent

In the popular imagination, I imagine, "honeycomb" is a gooey dripping amber chunk of honey with, somewhere inside it the hexagonal framework of the beeswax supporting it. In actual fact it rarely looks like this.
When first built wax comb is a crisp bone-white, one often sees it like this where bees have nested briefly out in the open on a branch. Sometimes they've only been there 48 hours before finding a new home but they've already build a few bright white blades of comb. Older comb that has been used to store honey is a creamy yellow and when full up of honey they seal the honey in with a snow-white layer of capping.
Bees use comb for two distinct purposes (mainly), there, the honey storage, but there's also "brood comb" where they raise new bees. Here in the core of the hive they ley eggs, which develop from little pieces of rice into larvae, which look like grubs, only cutely -- they do not creep around though but stay snug in their cell like you in a sleeping bag in a tent on a cold night. And then after six days the nurse bees put a cap over the cell and the young bee pupates in its cell, spinning a silk cocoon around itself (you don't think of bees making cocoons around themselves now do you). This brood comb is distinct from the honey comb, the cappings over the brood is not snowy white like the honey but a pleasing light brown in the youngest brood. Shortly it becomes a cinnomen red-brown and eventually, after a few years, a dark mohagony brown of dark chocolate. Along with this chocolatey color it is by this point no longer crisp and angular but thick with rounded edges. If you were to try to cut it with a knife you'd find it is also thick but yielding, again like chocolate, but also filled with the cellophane-like crinkling remnants of bee silk. And it's delicious like chocolate -- no not to you or I but to the "small hive beetle" (which looks like the lady bug's evil alter ego, all black), and the wax moth, whom we'll come back around to so stick a pin in it.
Where does beeswax come from, I hear you crying out into the void on many a dark night (in your tent). Young bees extrude it from four glands on the underside of their abdomen, they then detach these and mold them into the wax comb they is being built. Interestingly, it does not begin with the famous hexagons but begins with circles that then become hexagons through I suppose the morphological pressures pushing and pulling their walls.
Beeswax mainly consists of esters and saturated and unsaturated fatty acids -- WAIT WAIT I see your eyes glazing over, and let me tell you right now I haven't the faintest idea what an ester is either, but what I can tell you is beeswax readily absorbs most chemicals it comes in contact with, especially oils. As a result of this, old dark comb is full of all kinds of chemical build up from things the bees have brought into the hive. Debris including from the bees own cute little dirty feet as they come in from outside, gets absorbed into the beeswax (leading to a build up of a high amount of "proteinacious material" (read, delicious to moths and beetles, they be licking their lips just reading this), as well as the silk cocoon lining (silk is almost entirely protein). As a result of this build up, especially the latter one, the actual size of the inside of the cell gets progressively smaller, which causes the bees developing in the cells to be smaller, in one experiment bees emerging from 7 year old comb were only 55% as big as bees developing in fresh comb, and many other experiments how smaller bees are less productive. Ii imagine if they could talk they'd have really high pitched voices they'd be extremely self conscious about.
But let's get back to those wax moths for a moment, that find this old comb so delicious. Galleria of the galleriini They generally aren't present when there's a lot of bees, but if a hive has become empty of bees or nearly so is when they run riot. Their fat white grubs will burrow through that chocolatey old comb, rendering it into the sticky cobwebbing like the devil's cotton candy. Then the grumbs spin clusters of cocoons that have the consistency of styrofoam. Finally the emerge as drab and dim-witting moths that flutter about ineffectually but somehow find their way into more hives eventually. Many a beginning beekeeper has opened a hive to find its just been reduced to grey webbing and packing peanuts (would that be the peanut galleria). Experienced beekeepers learn this fate is easily avoided but still generally harbor a vindictive grudge against wax moths (I told you to stick a pin in them didn't I?)
We tend to lose track of the Old Ways, of how things were Before Us. What happens when people aren't manually rotating out old combs after all? Well, before we were keeping bees in boxes they tended to live in tree hollows. Established feral (naturally occurring) hives only live about six years (probably not a coincidence that that's about the point at which the comb becomes particularly too old), then the hive fails. The population dwindles away. A greater or lesser wax moth flutters drunkenly in for better or worse, and lays its nigh microscopic eggs all over, which soon become dozens and dozens of fat squirming grubs turning the wax into so much unsettlingly-sticky fluff, which they leave behind when they themselves go fluttering out to find more mischief. Now there's a cavity space full of fluff, which some mice or squirrels find make a snug home, until their activities have used up all the cursed cotton and left an empty cavity space ... perfect for reoccupation by a new swarm of bees. The natural cycle.
The man-managed cycle, meanwhile, requires that these old frames be painstakingly cleaned of the old comb. The old wax is either cut, melted or blasted with a pressure washer, to remove the comb from the wooden frame. This old wax weighs 5 times as much as new comb, precisely because it is now 80% stuff other than beeswax ("slumgum" its called), so even melting it down can feel unrewarding considering one is mostly getting this waste material. And then one needs to rewire the frames and put now straight pieces of "foundation" wax in them to guide the bees. Bees can obviously build on their own but with no guides they might not necessarily build straight enough on the frames.
So we know what we need to do, what we should do, as a good beekeeper, right? Change out those frames. But a few years ago I came up with a rather unorthodox solution. I do rotate those old frames out of the brood area to the honey boxes wherefrom they will be removed from the hive at harvest. But then, as they're sitting empty in storage in the shed waiting for the hives to be ready to receive them, ripe for nibbling my wax moths ...I, well, I don't mean to scandalize you but, well, I let them. Just a nibble. Going through them about once a month is frequent enough to catch the wax moth larvae having turned just a few square inches of the comb into hell-floof, which I remove. And those squirming grubs I pluck them out and toss them to the waiting magpies who come with heart shapes in their eyes. Repeated every so often until the whole core of the comb has been removed, I'm left with a frame with just a border of old comb, empty in the middle, not needing to be rewired. I haven't wasted any time mucking around but now have a frame I can put into a hive, and the bees will use the remaining edges as a guide to build the requisite straight comb.
The resultant comb will have swirls of dark chocolate brown whirled with the golden french vanilla coloured brand new comb like an ice cream of buzzing bees, or, perhaps, as I gaze fondly at it, I might say like a purring calico cat.
