What a  difference this year!  I stopped by some old black locust trees in 
ivy's  strangle-hold by the library today.  Some blossom clusters had 2-3 honey  
bees not counting wasps and butterflies.



On the Irish List we are conducting a survey of when the first ivy blossoms  
are seen as it seems to work from north to south and we aren't sure whether it 
 is light level (latitide) or temperature that is the trigger. Perhaps you 
could  let us know the latitude, altitude and current temperature range of your 
ivy  flowers as well as the first date you saw the blossoms open.
Thanks.
 
Chris
