#' @title Converts bee body length (mm) to total field nectar load (ul).
#' 
#' @description Calculates total field nectar load (ul) using body length (mm) from Henry & Rodet (2008).  
#' 
#' @param  BL vector of body length measurements (mm).
#'
#' @return A dataframe with bee total field nectar load (ul) is returned for each specimen.
