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.

Hello,
I'm curious if anyone has seen bees or flies on their Galanthus? I
have no flowers here here so far, just lots of leaves appearing
everywhere. Anecdotes say Galanthus are "good early bulbs for bees"
but I have never witnessed this myself, and I want to know if it's
true. Seems like it would be too cold for bees. Flies maybe? What
could the natural pollinators be of such an early blooming flower?
A good question for the galanthophiles: are Galanthus self-compatible
or do they require outcrossing to set seed?
