There are currently 154 species of bees known from Blandy Experimental Farm (out of >900 in the eastern USA. 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 8175 identified specimens caught by net or traps on site.
