Table I
Distance values for the recorded foraging flights of Chelostoma florisomne. The direct minimum distance represents the distance to the closest host plant stand from each nesting site. The direct foraging distance (d) was calculated from the horizontal linear distance (h) between nesting site and place of recapture and the difference in altitude (a) applying the formula of Pythagoras (see text). The direct distance across forest represents the distance a bee had to fly over or through forest. All distance values are given in meters. Foraging flights nos. 9 and 10, nos. 16 and 20, as well as nos. 18 and 19 were by one female each.
