There are currently 143 species of bees known to occur at Blandy Experimental Farm (out of >900 in the eastern USA and 352 in Virginia). This number will undoubtedly increase as more species from difficult groups (e.g., Andrena) are identified and more sampling is done early and late in the season. These data are derived from a total of 3261 identified specimens caught by net or pan traps on site.
