Willows are used as examples of transitions from insect to wind pollination but the hard data isn't terribly convincing. Some say that some male catkins on some Salix species secrete nectar while others say they don't. Can you see the workers insert their tongues into the bases of the individual florets? Likewise, I'd really like to see some convincing footage of bees taking nectar(?) on female catkins when the stigmas are receptive to pollen. Here in America, you can see certain butterflies (like mourning cloaks) coming out of hibernation to forage on male catkins on warm February days. I've seen them on the European pussy willows (S. discolor?) that have escaped from gardens and are growing wild in wetter areas. <div><br></div><div>Peter Bernhardt</div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Tue, Feb 17, 2015 at 11:57 AM, Kevin Lindegaard <span dir="ltr"><<a href="mailto:kevin@crops4energy.co.uk" target="_blank">kevin@crops4energy.co.uk</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr"><span style="background-color:rgb(246,246,246)"><font color="#333333"><span style="line-height:17px">I took this video (<a href="https://www.youtube.com/watch?v=Zi5cu5CSHt4&feature=youtu.be" target="_blank">https://www.youtube.com/watch?v=Zi5cu5CSHt4&feature=youtu.be</a>) today (17th Feb) showing several different types of bees foraging on a male willow plant.
