Sweet…I mean, SWEAT Bee

More OMGSHINY (actually, I think this one qualifies as “HECKASHINY”) from the bird sanctuary:

A large mossy log, lying prone, begged to be rolled.  A small piece of the rotting wood broke away in my hand, revealing the tunnels and chambers and frass of its inhabitants.  A bright flash of iridescent green caught my eye; but it was only a small piece of abdominal segment, not a whole animal.   A strange thing to find in a log, though, I thought.  I briefly wondered what it might be, then returned to the task at hand: a better grip, and one…two…three…roll.

Another tiny flash of otherworldly green…this time, attached to a living creature:

Shimmering like a jewel in the morning sun, this tiny Sweat Bee stirred sleepily.  After a brief stroll in her newly aerated world, she paused to carefully groom her cheek:

Sweat Bees (Halictidae) are so named because of the affinity of some species to lap persperation off of human skin.  Although many are brownish, some, like this one (Augochlora pura), are vibrant green or blue (especially females), while others boast yellow and black colouration (especially males).  They are usually quite docile, but can sting if threatened…although the sting is not much more than a tiny pinch.  I was quite surprised to find her here beneath a log…but I have learned that a very few Halictids (including this species) use rotting wood as their nesting sites.  Females, like this one, will also overwinter in wood (just like my wife’s recent wasp find).  Most Halictids, however, nest in soil.

I am rather enamoured with the way the tiny droplets of moisture on her head and thorax come across as aquamarine blue…a play of the light on her irridescent exoskeleton…

    Now there’s an insect which is worthy of an “ahh cute” prefix!

    Are these taken with the Canon? They’re great. And this is an adorable bug. 🙂

    These are some of my favorite insects, by far. The coloring is spectacular. I too found a few females that had taken up residence in an old Maple Tree stump. I would peel back the bark and almost always find one. Curious little creatures aren’t they?

    Fantastic shots! She’s quite stunning. I’m glad you decided to see if anything of interest was lurking in the log.

      Thanks, Jason! There are ALWAYS goodies to be found in/under logs…I’ll be searching there more often now that things are thawing out…

    the photos captured are exceptional! I came across these while photographing wild lobelia. Try as I might, with tripod, zoom lens, any setting I could, I have not yet managed such good photos! These move so very fast. They are stunning in emerald!
