Blue Honey

Did my last inspection/consolidation today in the warm weather.
One hive had an unusual situation; 4 frames of blue/purple honey. That was noteworthy enough, but around each semi-circle of this unusually coloured honey there were were clusters of dead bees.
I am wondering if they got a 'last-blast' of nectar from the blue Monkshood, Aconitum sp.?
The colour was evocative of that delphinin blue.
I never observed honeys at any time on the flowers, just Bumbles.
Ever have bees store 'toxic' nectar. No Ag in the area so not concerned with mass pesticides. That blue colour though...?

It is known to happen, particularly with grayanotoxin when bees collect nectar from certain members of the rhododendron family.

Thanks BBK, no Rhodos here, maybe a few in June somewhere around. I think its the Aconitums, they bloom late and have that deep blue-purple colour. Also have some toxicity, to all bugs, not just bees.
Does anyone think I should pull that honey or just LeaverB? See what transpires? That would be my default position; the bees collected it, the bees should know...

I don't think I have seen any examples of nectar and the resultant honey resembling the color of any blooms. I *have* seen bees collect colored sugar syrup used to feed hummingbirds, and the resultant concentration retaining the color- I was a little freaked-out the first time because it was a patch of blood red amongst normal honey. It took a bit of thought to discover the cause.

I would not assume that the bees "know", and if there are dead bees together with the unusual color I would be concerned.

Thanks BBK, I have a warm day forecast this next week and will re-assess. I can pull those frames to see if there are more dead bees. All dead bees removed last inspection.
The colour is just a band or arch across the top of the few frames. I feed hummers every year but no colour added.
No county fair with blue candy floss within 5 miles this summer.
Maybe will sample and see if I can get some tests done. How hard could that be? LOL

So, the re-assessment of blue honey hasn't happened yet; see my Bears post.
Should be warm tomorrow and Saturday. Will get in and look again.

No more dead bees around the blue honey arc. Maybe they're just leaving it alone. Checked 4 days ago.
Hives are tucked in for Winter. Will find out in Spring if it was "bad".
Done and dusted for this year. Going to serious negative temperatures this week.
Snowed all day, nasty NNW wind, temperature dropping fast now.
