DO YOU KNOW NATIVE BEES?
NATIVE BEES: AN IGNORED RECOURSE.
While the
domestic bee is being decimated by a number of environmental and biological
causes, it may be that the future of the world’s food security lies with the
humble native species that almost nobody is aware of. Read more ….

THE SECRET LIFE OF NATIVE BEES (from an article by Enrique Gili, Dec. 19, 2013
As colony
collapse disorder takes its toll on honeybees, native bees draw attention as an
insurance policy for future food security. Bees, wasps and other species they interact
with, the group has evidence suggesting native species are surprisingly robust,
despite the downward trend in pollinator populations on the whole.
This is
a bright spot amid the dire news heard recently about domesticated honeybees —
the demise of hives due to an onslaught of environmental and biological
threats. “We’re lacking a lot of data,” says Sam Droege, director of the USGS
Bee Inventory and Monitoring Lab, a fact confirmed by a recent report published by the
Congressional Research Service.
Unlike
honeybees, most native species lead solitary lives. Some occupy nooks and
crannies in the landscape, such as hollowed out logs, or burrow into the
ground. The vast majority of native bee species pass unheeded or undetected by
humans. Scant attention has been paid to them, despite the urgency surrounding
CCD.
Native
bees, for their part, participate in pollinating 70 percent of the world’s
flowering plants along with other native pollinators. Some 26,000 farmers and land managers in the
USA have been trained on ways to enhance native bee habitats, publishing
evidence-based guidelines on various ways farmers can attract native bees and
other beneficial insects to their land and, as a result, also mitigate or
reduce pesticide use by attracting small predators, such as flies, wasps and
beetles that consume pests known to infest farmers’ crops.
(*) Xylocopa mordax
(Caustic Carpenter Bee). The iridescent hue of the wings is known as wing
interference patterns, or WIPS. Light bounces off transparent wings, which are
made of chitin, to create unusual colors similar to those seen in soap bubbles.
Serrations on the wings are a sign of aging. Check out “The Wild Ones” on Ensia, a photo slideshow of some of the species included in
the Bee Monitoring and Inventory Lab’s database.
Note of the Editor: More attention is paid in Europe to the native bees; farmers
offer artificial sites to favor native bees’ natural reproduction.
