Why have they done this?

Photo of a brood frame and it’s not the first time I’ve seen this in a brood frame, it looks like where the cells are made over the wire there is less brood been reared for what reason ?

I have seen it in the past and also get a similar scenario with foundationless frames when using kebab skewers for wax buidling support. Fishing line isn't such an issue as my lot tend to chew them away.

Maybe the metal gets too warm

Maybe it just interferes with the cell architecture - like if you had a steel beam too low in your living room and had to duck underneath every time you crossed the room!!

No idea. Most of my brood frames have looked like this all the years I’ve been keeping bees. Never seen it over fishing line

This is an interesting theory on the question. I've seen this many times. After a few rounds of brood, the issue disappears.

I agree, don't tend to see it in older frames.

Very interesting insights.

Quite a good photo of it here and he also suggests it goes with time.

All my frames look like this until they're well used.

Or too cold

Or too cold

Yup, basically the wire acts as a heat sink and the queen (or the bees who prepare cells for the queento lay in) notice this.

There are people who claim that it's not a problem with stainless wire, only the zinc-coated(?) steel stuff used in of the cheaper less expensive foundation. I have no idea if that's true or not.

It's a different system here where you don't buy foundation with wire in it. I use stainless wire and wire my own frames, embedding the foundation into it, and I see it. I always thought it was to do with the wire tending to muck up the base of the cell so the queen avoids laying in it. I thought that after a while the workers eventually manage to smooth the base out enough.
