Dear All,                Aug 6, 2007
    This seems to be a good year for 5-fingered Ivy (_Parthenocissus 
quinquefolia_) because Bees (and some Wasps) are unusually attentive 
(unless I have missed this feeding previously) where the plant has good 
light exposure and has flowered well. [The same species growing up a 
wall that faces 30o E of N has never flowered; could be a combination of 
recurrent pruning as well as light exposure in this case.]

    About a week ago many Bumble Bees (50-100) were working Ivy that has 
grown up a Black Cherry and this continued off and on for several days. 
On Aug 4 we saw many Bumble Bees, several Honey Bees and Yellow Jackets 
in town, working _P. quinquefolia_ that has grown along a wire fence. 
There were many immature fruit but no flowers at this point so nectaries 
at the base of the ovary may continue to be active after the corolla is 
shed. Or it may be just residual nectar. 

Yt, Dave Webster, Kentville
