Nectar production rates and colours of 75 flower species observed to be visited by Bombus terrestris terrestris (Linneaus 1758) workers near Würzburg (Bavaria, Germany) were measured between 1999 and 2002. Production rates were calculated for each flower species from the volume and concentration of nectar produced by 30-60 flowers per species over a 3 hour period during which visitation was prevented. The average amount of sugar produced (μg in 24 hours) is given below for each flower species. The spectral reflectance of all flower species were quantifiled, converted into bee colour space loci [Chittka & Kevan 2005] and placed into one of six bee-subjective colour categories: blue, blue-green, green, ultraviolet, uv-blue or uv-green.
