Purple asters and honey bee

After the last few years, anytime I see a honeybee I feel a little progress has been made moving back from the brink. Colony collapse disorder has decimated their ranks. Last evening I saw not one but two different honeybees flitting through the purple asters. It’s possible that both bees are from the neighboring orchard, just a mile away through the woods. It’s just as possible, perhaps even more likely, that these are wild or at least feral bees with a hive of their own not far away.

Some of the more recent research on bees suggests that the colony collapse disorder didn’t affect wild bees as much as it has the domestic ones used by beekeepers. Since the disorder is related to or caused by pesticide levels and other toxins, it makes sense that wild bees would be less affected. Wild bees are much harder to study, and the research on them is limited, even to the point of not always knowing ranges and the species within a range.

In any event, this honey bee and its partner over on the next batch of asters seemed happy enough and didn’t mind that I got close to them to take photos. I didn’t even see the bees at first, deep as they were in the small blooms.

Purple asters are also called fall asters around here, and fall arrived on Roundtop Mtn. a week or so ago, despite the calendar not catching up to the “boots on the ground” reality until Saturday. It’s time to put away the last of the short-sleeved shirts and bring out the long sleeves. The cats, who abandoned my bed during summer, are back and cuddled tight against me at night. It must be like sleeping in a straight jacket as I have no room to turn at all. Who knew a couple of 8 lb cats could be so impossible to move?

Evening and early morning now requires a sweatshirt. The golden delicious apples will soon be ready; perhaps the first will be available this weekend. The leaves haven’t started turning yet, but with these cool evenings that can’t be far away. This weekend will be time to bring in the plants that summered outside and add another bird feeder to the deck. Fall is here.

Honey bees are buzzing at Roundtop

I know I said I wouldn’t post any more photos of non-native plants, so please try to ignore the invasive black knapweed and focus instead on the honey bee on one of its purple flowers. By this time, anyone who has been paying attention has likely heard about colony collapse disorder that’s been killing bees around the world, especially in North America and Europe.

So far, here at Roundtop, my impression is that honey bees are in good supply. Truthfully, I never paid too much attention to the number of bees until I started hearing about colonies collapsing, but I believe I have a general sense of them—at least enough to notice if suddenly I didn’t have many.

Instead, I seem to have a normal or perhaps even a slightly higher than normal number of them this summer. In the past Pennsylvania has experienced severe losses of bees for non-colony collapse disorder reasons. For example, during the winter of 2000-2001, nearly 50% of the bees disappeared, though natural winter losses are typically in the 15-25% range, according to Penn State University. The Colony Collapse Disorder Working Group is based at PSU.

CCD, as it’s come to be abbreviated, is still incompletely understood, with researchers now believing that many causes contribute. Focus is on everything from mites, a virus, fungus, cell phones, nicotine pesticides and bacteria that might somehow all work together to suppress the bee’s immune system.

Researchers also indicate that propagation of the CCD is much like a contagious disease in how it spreads. Healthy bees become contaminated with CCD when they enter a diseased colony’s hive to rob its provisions for their own use. Even climate change is implicated in CCD, with suggestions that it has made bee hives more vulnerable. As plants are now blooming at different times of the year, nectar flows are also much earlier and this may contribute to increased bee stress. At this point, climate change is not considered to be a direct cause of CCD.

The most recent information I’ve found is located here, a preliminary report published in mid-May. Total colony losses in the U.S. for ’08-09 are just under 29% of managed bee colonies, a reduction over the two previous years. In those years, bee colony loss was at nearly 36% and 32%. While this sounds like an improvement, researchers note that the rate of loss is unsustainable. Still, colonies lost from CCD symptoms last year was put at 15%, compared with 60% during the previous winter.

Bees can roam pretty long distances—several miles from the hive. As Roundtop is about a mile from one edge of an apple orchard, many of the bees I see are likely from their hives, though I have also seen several wild (or perhaps escaped) hives down in the woods this year. In any event, seeing bees is now something I pay more attention to than I used to, and I’m glad that there seems to be plenty around to look at.
