They are among America's busiest workers but they've been declining sharply in recent years due to various factors, including pesticides, mite infestations and loss of genetic diversity. Now Faith Karimi writes at CNN that President Obama has created a task force to address the issue of rapidly diminishing honey bees and other pollinators. "The problem is serious and requires immediate attention to ensure the sustainability of our food production systems, avoid additional economic impact on the agricultural sector, and protect the health of the environment," Obama said in a memo was sent to Cabinet secretaries and agency heads.
Friends of the Earth says that the US needs to immediately ban the use of neonicotinoids, a class of pesticides chemically similar to nicotine that has been linked to bee deaths. "The administration should prevent the release and use of these toxic pesticides until determined safe," says Erich Pica whose organization is conducting a campaign and has collected more than half a million petition signatures asking Home Depot and Lowe's to stop selling plants treated with neonicotinoids (neonics). So why isn't the US moving more quickly to ban neonics? Neonics play "a major role in pest management for pest control, agriculture and the ornamental plant protection industries. They serve as a group of highly effective insecticides with low risk to people and birds, which can be applied systemically to the soil," notes a Texas A&M AgriLife Extension blogger. This is a safer, better pesticide than many alternatives.
Another reason to hold off on a ban: There are still doubts that neonics are the principal cause of bee colony collapse. "In other words, while neonics might be one of the precipitating causes, they might not be the principle cause of colony collapse disorder (CCD) in the US and Europe," says David Clark Scott. "Saving the honey bees may require a more complex solution than banning one group of insecticides. And it may require more investigation into other possible causes of CCD, including parasites, viruses, climate change, bee nutrition, lack of genetic diversity and bee keeping practices."

It's getting to be more grass than alfalfa, far as I see in the fields and as hay for sale (likely a matter of the spike in energy prices making water expensive to pump -- alfalfa needs irrigation here). And there are all sorts of bugs that live on alfalfa and crawl into the blossoms. But more to the point, alfalfa isn't generally grown for seed, so outside of those few who do produce seed, no one cares if it "sets a crop".
And there is no Alkibiades to come back and save us from ourselves.

Good point about not needing seed.

A specialty crop, being the seeds are tiny, and you can't exactly process 'em with a baler. Now that you mention it I'll have to look into that... it sets seeds randomly from first bloom til hard frost. They don't even mature at the same pace within a single flower head.
The primary insects I see on alfalfa blooms are a very small black bee and one that looks like a tiny black earwig, both very plentiful in hot weather.

50 million kilos of alfalfa seed a year are produced in N. America so not that much of a specialty crop. Seems that alfalfa leaf miner bees were domesticated mostly for pollinating alfalfa, at least here in Canada and I'd guess the small bees you see are also a species of leaf miner bee. There are a lot of leaf miner bee species.
