Lasioglossum tenax. A northern species, in general, but this particular one found at the southern edge of its range in the mountains of North Carolina. Range-wise you will find (if you were to look) L. tenax from Newfoundland to Alaska and down the spine of the Rockies where it stops about the same latitude as it does in Appalachia. The food for this bee, of course, is pollen, which, if you recall, comes from flowers. Now then, the flowers in Appalachia are for sure unsimilar to those in Alaska and the Rockies. So, does that mean L. tenax is unpicky about its pollen? Probably not, probably, as is suspected for most of these Dialictusy Lasioglossums, they should be generalists. All sorts of pollen should be ok. So, then what limits them? Why, for example, don't they hang out in Fort Lauderdale, Austin, or Petaluma? And why are there so many of these Lasioglossum generalists running around in the same place? Why don't they just compete each other up? Maybe there is just so much pollen out there that multiple generalists can co-exist on the same food sources? What exactly is the niche here for these things? So many Lasioglossum species just should not exist in one place, (metaphorically this is similar to the apocryphal story that bumbles should theoretically should not be able to fly). Why are we going to Mars when we can't even figure out the Lasioglossum problem? 8 "?"s today. Might be a record. 13:19, 14 May 2021 (UTC)13:19, 14 May 2021 (UTC){{{{{{0}}}}}}13:19, 14 May 2021 (UTC)13:19, 14 May 2021 (UTC) All photographs are public domain, feel free to download and use as you wish.
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. - Oscar Wilde
