Galanthus and bees

As several people have confirmed, honey bees (and other insects) visit 
snowdrops whenever temperatures are high enough. Snowdrops are 
out-crossing, and buzz-pollinated with poricidal anthers.

When mentioning this in talks audience members have frequently expressed 
surprise that bees and snowdrops coincide. My reply is always that they 
do, even in UK, but in many places where they grow wild they come into 
flower much later (March/April) as the snow melts. Ambient temperatures 
are then very much higher than in England in February and insects are 
consequently much more active. No doubt too, the flowers are much more 
ephemeral, rather than lasting for weeks as they do here.
