Bee Balm Bee Balm Bee Balm Bee Balm. Dufourea monardae. See this bee, it is small and only hangs out on Bee Balm. Look. Look at its tongue. That is a long tongue. Look at Monarda fistulosa (this bee's fav, and perhaps only pollen plant). Ah, those are long individual florets (or whatever the proper term is). Now why are there hairs along the length, but the very tip is bare? Other bees just have a brush, or seemingly none, or scattered hairs, or short hairs, ... pretty much all combinations. Surely someone has looked at tongueitecture of the hairs on bees, but, sadly, I know little of bee tongues (but do have the belief that the hairs are used to "trap" nectar on the tongue). Length of tongue is all over the bee literature and measuring and describing the palps (long topic) on the tongue is great sport among the old taxonomists. But what about those hairs?

We Are Made One with What We Touch and See

We are resolved into the supreme air, We are made one with what we touch and see, With our heart's blood each crimson sun is fair, With our young lives each spring impassioned tree Flames into green, the wildest beasts that range The moor our kinsmen are, all life is one, and all is change.
