Crypsis Challenge #1 Reveal
July 2, 2010 | Twelvestones, Roswell, GA, USA
Did you spot the hidden critter from this earlier post? No one commented, but I’ll go ahead and reveal the answer.
There’s a hint about two thirds of the way down on the left hand side. That’s a lacewing egg on a thread. And just to the right of that is the creature itself, a trash carrying lacewing larva. I circled the two in red below.

Still having trouble seeing it? Try this side view.

Of course, all you can really see is the debris. To see the actual critter, you have to turn it over, as I did here.

Reptile Day 2010 at Fernbank Museum
Fernbank Museum, a local natural history museum, opened in Atlanta in 1992. Its predecessor, the Fernbank science center, opened in 1967 and remains open today.  I have vivid memories of visiting the science center as a school kid. They both grew out of an effort that began in 1938 to preserve what had become known as Fernbank forest, 65 acres of old-growth urban Piedmont forest.
Fernbank Museum Entrance
I had been wanting to check out a special gecko exhibition at the museum. When I saw yesterday would be Reptile day, I knew it was time to visit. As a bonus, I saw online that there would also be a special exhibition of nature photography by local photographer Bill Harbin.

Hatched Coreid Eggs
June 26, 2010 | Twelvestones, Roswell, GA, USA
I spotted these hatched eggs while strolling through a local park. I like how they have a sort of dashed “break here to exit” line at one end. I also like how you can see the cell structure making up the eggs, a bunch of little hexagons. I only wished I’d found them before they hatched.
I’m not really happy with this photo. I really need some way to easily diffuse my flash in the field. Not only are there flash hotspots, but you can actually see a recognizable reflection of the camera on each shell. Nonetheless, I thought the eggs themselves were worthy of a post.

Parasitic Wasp Stalking Tumbling Flower Beetle
June 14, 2009 | Twelvestones, Roswell, GA, USA
As usual, I was working in the yard when I got distracted by some sort of dramatic natural scene. This time, I noticed that some magnolia blooms were literally crawling with tumbling flower beetles. Mostly, there was a lot of mating going on amongst the beetles. Then I noticed this little wasp that kept approaching various beetles, usually resulting in the beetle running off. Finally, she found one that was less wary. Above the wasp is closing in. Below, it appears she eventually made contact.

Jumping Spider Subdues Carpenter Ant
June 16, 2009 | Twelvestones, Roswell, GA, USA
I found this pair on a viburnum in my backyard. What looks like a male Phidippus whitmani has subdued what I assume is a winged reproductive carpenter ant.
I didn’t notice while I was taking pictures, but while reviewing them I saw that a little fly arrived to share in the spoils.

Crypsis Challenge #1
July 2, 2010 | Twelvestones, Roswell, GA, USA
I plan to regularly post challenges like this. Can you find what’s hidden in this photo? I’ll follow-up with more info in a subsequent post. Again, I’m posting this before the site is public, so I’ll wait until I have some guesses in the comments before revealing the answer.

Tube-tailed Thrips
Tube-tailed thrips larvae | May 17, 2008 | Twelvestones, Roswell, GA, USA
I spotted this scene on a small stump in my front yard. At the time I didn’t know what they were. After a bit of research, I determined they were tube-tailed thrips from the family Phlaeothripidae.
I assume there are so many because they’ve found a good food source, fungus perhaps. I’m curious as to why the larvae are orange-ish red. Occasionally I’d see a black adult like the one below, which definitely contrasts with the color of the larvae.

White-marked Tussock Moth
I often encounter the easily recognized White-marked Tussock moth, Orgyia leucostigma. I found this one feeding on maple at the end of May in my front yard.
May 31, 2010 | Twelvestones, Roswell, GA, USA | ~30mm
I grabbed it for some closeup shots and to attempt to rear it.

It must have been a final instar, because it pupated just five days later. It spun the cocoon at the top of a container, but I carefully removed it to take some photos.

A flightless female emerged ten days later.
It's a female! | June 16, 2010 | ~15mm

Females cling to the cocoon until mated. That night, I carefully pinned the cocoon with her on it to a post on my deck. When I checked an hour later, mating was already in progress. The male that found her was rough looking, having lost many wing scales.

Identification Challenge #1
May 23, 2010 | Twelvestones, Roswell, GA, USA | ~10mm
I’ll be posting identification challenges like this periodically. Feel free to comment with your guess.
As I’m posting this before the site is public, it may be awhile before I post the answer to this one. I’ll wait until I see some comments here or until a reasonable amount of time has passed.

Twelvestones
For my first post I want to talk about the where I live, since many of the photographs will be from here. My intention going forward is to link a photograph back to one of these “Location Profile” posts about where the photo was taken.
Google satellite image - Taken in Spring 2010 I think
Location
I currently live in Twelvestones subdivision in Roswell, a northern suburb of Atlanta, Georgia. Twelvestones, therefore, will be my shorthand for this home and places close by.
We’re on the Piedmont Plateau at an elevation of around 1000ft (300m), latitude 33.99911, longitude -84.29031. The house faces northwest, giving us a nice southern exposure on the back.
