Hylaeus basalis, m, left_2020-08-19-15.57.57 ZS PMax UDR

Description:

Check out the base of the antennae on this bad boy. Technically this segment is called the scape (hmmm, so close to "Snape" but, well, ...nevermind). Under most North American bee models this segment is about the same width as the flagellar segments (some departures in Nomada mostly because the pedicel (the small ball joint segment after the scape) is sometimes recessed into the top of the scape (this is probably too much information, so am stopping here on that super interesting topic)). Across all the bees (that at least come to my mind) scape dimensions are pretty darn similar, even if the flagellar segments are super long (like male Eucera) scapes are scapes and conform in mathematical regular proportion to the bee's head across beedom (males almost always with relatively shorter scapes from some reason (why would this bee given that they have wave around an extra antennal segment and often have long antennae...or, is that the point, short antennae are stronger?). Now that I am thinking about scapes I am thinking that they must mostly be structural, holding up and perhaps containing muscles that control the flagellar segments which are full of bee sensors (Aside: isn't its amazing what you can think of in the absence of evidence?). OK back they Hylaeus, the females all have the basic bee scape shape and size, but the males can vary from regular size to what you see here: something grossly monstrous in size that it just seem wrong. Is this really all about selection by lady Hylaues basalis or is there something else? Unclear. Anyway, as I write this a vision of an entire PhD arises, awaiting the proper person on the spectrum who can sit and measure bee dimensions all day.
