The people have spoken! More Scutums. A few pictures ago we showed the ultragreen back (aka the scutum) section of Augochlora pura indicating that with the right mojo you could tell this species from the similarish genus Augochlorella with but a glance. And. We did not show you a picture of the scuticular characteristics of an Augochlorella because no on had taken that picture. So, today Elizabeth Panner has obliged the thousands of people who have been clamoring for just that picture. So, let's look at this Augoclamorella picture and compare (use the little mid-line trough on the scutum as reference, it points to the head (why a bee has this line is mysterious, its not used hardly at all as a character to separate one species from another in bee taxonomy and it just might be the case that all species have this line (someone idle should look at all the bee species in the world to verify this))). Alright, so, in contrast to the uniform plain of equallishly spaced pits in A.p., A.a. starts out in quite a similar pitted pattern, but as you move towards the head you see the pits begin to coalesce, lapping one another until, in their lapping frenzy, they devolve into a glittering moonscape of cratered metallic topography. So, now you know that you need only glance at the always-easy-to-find-under-the-microscope back of a small green bee to smugly self-validate your superiority to the rest of the human race. You do have to eliminate equally green Agapostemon and Augochloropsis, but you already know how to do that. ~~~~~~~~~~{{{{{{0}}}}}}~~~~~~~~~~

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.

USGSBIML Photoshopping Technique: Note that we now have added using the burn tool at 50% opacity set to shadows to clean up the halos that bleed into the black background from "hot" color sections of the picture.
