  • Hi, Bee Group - I am looking for a non-invasive method to observe underground bee nests, specifically nest architecture, reproductive biology, food provisions, presence of parasites, overall health, etc. There is a new technique (diagnostic radioentomology) to do these things with portable hives (like adobe blocks). If one wanted to do the same with nests in situ , would a field x...

  • Hi, Bee Folk - I am looking to chart the spread of Anthophora plumipes (formerly A. pilipes ) that was brought over from Japan in the late 1980s as a potential pollinator of early spring crops in the northeast U.S. According to discoverlife.org and correspondence with David Biddinger from Penn State, its range now includes MD, VA, DC and PA. If you happen to have caught any of...

  • This is an interesting topic that came up in a local naturalist blog. It seems applicable to bees, too, so thought it worth sharing here. The attached study focused on sodium uptake of milkweed and oaks near roadsides and any potential affects on butterflies. Interestingly males and females responded differently to increases of this historically limited micronutrient. Males...

  • Hi, All – Thanks to yet another snowstorm, I had a chance to try the camera platform mentioned below. http://petapixel.com/2013/10/19/turn-smartphone-microscope-macro-photography-rig-10/ The attached pics were taken with an iPhone 5. If you're looking for an inexpensive way to take decent close-up shots, this platform is a great tool. It's rather fun to experiment with, too...

  • Hi, Bee Folk - A MD Master Naturalist is seeking advise for her neighbors on how to reside peacefully w/ ground-nesting bees. Here's what she wrote: "Further to the excellent copperhead discussion, I could use some input for my neighbors. Our neighborhood is an older suburb, but has an unusual amount of wildlife. Does anyone know of a peaceful solution such as was found for the...

  • Hi, Everyone - As part of my thesis study, I need to build 90 bee exclosure cages for soybeans that typically grow to about 3.5' tall. So far the plan is to use 4' wooden garden stakes and grow cover cloth. This is going to be a bit costly though, in part because 4' garden stakes don't seem to be sold in bulk at the local hardware stores (Home Depot and Lowes). Have any of you had...

  • Hello, Would anyone happen to know if there's GIS data for N American bees? So far, I've found maps for Africanized bees but none related to our native bees. A Google search, also led to a brief description of this intersting thesis proposal: A GIS-Based Landscape Scale Model for Native Bee Habitat by Andrew Scott Foy Alas, it is available only to the VA Tech Campus network, which...

  • Hello, All – In preparation for an upcoming project, I am trying to gather info on bee species that pollinate soybeans. While these legumes are self-pollinating, a few studies indicate that their yield is enhanced by insect pollination. A study conducted in Indiana USA (Ortiz-Perez et al. 2007) used alfalfa leaf cutter bees (Megachile rotundata F.) Another experiment carried out...
