I would think that they have plenty of time this summer to figure it out before cool temperatures.

I wonder how much heavier a log is with bees and honey in it. The one we did, not too bad because of how tight the cavity was...

Tulip poplar honey on left....pure sourwood on the right
I think honey weighs 12 pounds per gallon

Interwebs is giving me fits this morning........ Lag lag lag...
Ok .. See them now John and deleted my double posts
I should get a picture of tar weed honey... Looks like molasses. Not my favourite at all.
I was about raised on orange blossom honey. Grandma had an orchard and grandpa harvested the hives in the orchard.

The forum is dragging ass today - Ipowerweb must be having issues.

Takes about 45-50 seconds for a page to load on the forum today. Same if I post, then sometimes it will double post due to the auto save

It's Ipowerweb - it'll get back to normal eventually.
Bees may be addicted to harmful pesticide
RACHEL FELTMAN, WASHINGTON POST

A pair of new studies published last week in Nature are disturbing when taken separately, but so much more chilling when laid out next to each other.
The first provides new evidence that a relatively recent class of insecticides known as neonicotinoids can have a negative effect on bees, adding weight to the theory that these chemicals could contribute to colony collapse disorder and endanger our food supply.
In the second study, another group of researchers found that bees don't avoid these harmful pesticides. They may actually seek them out and become addicted.
Recent years have seen bee populations on the decline. That's bad news for us, as Whole Foods recently highlighted by removing from one of their salad bars every product that relies on healthy pollinators.
While the jury is far from in, some researchers point to neonicotinoids, which have been banned in Britain for two years but are still widely used in the United States, as a potential culprit. These nicotine-related insecticides are favored for their relative safety to humans, because they target specific nerve receptors in invertebrates. But while they're safe for humans in the short term, some studies have argued that they're killing off bees on a scale so large that our food security is threatened.
In the first of the two latest studies, researchers tried to determine whether the negative effects seen in bees exposed to neonicotinoids in the lab can be replicated in the real world. Led by Maj Rundlöf of Lund University, researchers used 16 fields planted with canola - eight with neonicotinoids and eight without - across Sweden. They studied colonies of honeybees and bumblebees as well as several individuals from solitary bee species, and they also monitored wild bees living in the area.
Honeybees didn't seem badly affected. But bumblebees had slower colony growth rates in the treated fields, and there were fewer wild bees, too. Additionally, none of the solitary females in the treated fields were able to breed as expected, while six of the eight untreated fields saw normal birthing habits.
What's especially troubling about this, the researchers pointed out, is that honeybees - which seemed fairly immune to any negative effects - are the species usually used to test chemicals.
While the study isn't universally damning for the pesticide, it indicates that researchers may not be able to predict how "bees" will react to neonicotinoids using just one species.
But maybe bees know to avoid neonicotinoids? Not so, according to Nature's second new study.
Researchers at Newcastle University and Trinity College Dublin found that bees are actually attracted to the poison. When presented with a choice between sugar and sugar mixed with the pesticide - which is bitter, a taste that scientists had hoped bees would avoid - the insects didn't show any indication that they could taste a difference. They didn't avoid the pesticide-laced food, and their taste neurons didn't seem to make a distinction between the two options.
And bumblebees, which seem to have more to lose, were even more likely to eat the pesticides than honeybees. They might even be addicted to the stuff.
"Bees can't taste neonicotinoids in their food and therefore do not avoid these pesticides. This is putting them at risk of poisoning when they eat contaminated nectar," lead author Geraldine Wright said. "Even worse, we now have evidence that bees prefer to eat pesticide-contaminated food."
