Globular Stink Bug Invasive

Posted on September 26, 2010 by Troy Bartlett

This post’s featured creature is Megacopta Cribraria.

August 5, 2010 | Twelvestones, Roswell, GA, USA | ~5mm

Just outside the entrance to my subdivision, there’s a stand of kudzu, Pueraria montana var. lobata, at the border of a city park. If you’re not familiar with kudzu, it’s a major invasive here in the Southeast that pretty much takes over wherever it manages to take root. Many of the volunteer outings with the local nature conservancy are focused on eliminating this invasive from conservancy lands. Here are a few photos of the area to give you an idea. read more

Who knew a mosquito could be so attractive? Looks like a male based on those plumose antennae.

I really have no idea what’s responsible for this odd sweptback cocoon.

Spittlebugs sans Spittle

Isn’t it cool to see these normally hidden spittlebugs exposed like this?

These spittlebugs surprised me by having no bubbles present to camouflage them. I have a few theories about what’s going on here, but it’s all speculation.

Their orange color suggests they might be unappetizing in some way. Or maybe that sap flow itself is poisonous. Of course, they drink it, but that doesn’t mean they haven’t evolved an immunity and that the toxin isn’t broken down once ingested. read more

Late Summer Luna Moth

Twelvestones, Roswell, GA, USA | August 22, 2010

I spotted this luna moth while returning from a walk in a nearby park. It was at the base of some landscape timbers, maybe having just eclosed. I coaxed it onto a finger and brought it home. I picked these grass blades as a perch and took a variety of photos.

After dark I found a spot where I could get the nearly full moon in the photo. There’s no way to get both the moth and the moon in focus at the same time, so I simply took one photo with the moon in focus and another with the moth in focus, and then combined them digitally. read more

This one looks like it has been doing push-ups on that leaf. Check out those foreleg femurs!

Patterns in Beech Leaves

Posted on September 12, 2010 by Troy Bartlett

Looking up from a forest trail at a nearby nature center, I saw the leaves of a beech tree backlit by the afternoon sun. I picked off a few of the interesting ones and held them by hand so as to take some closeups. I find the patterns interesting in the same way ink blots are interesting.

What do you see in these abstract images?

Mandelbrot Fractal Set?

Stained glass window?

Leaf within a leaf?

What do you see?

Can anyone explain what’s going on here? Is this how leaves start to turn in the fall? A disease of some sort?

Dagger Fly with Prey

Posted on September 11, 2010 by Troy Bartlett

Awhile back, Alex Wild posted some shots of dagger flies. I commented at the time that I had recently seen and photographed the flies, but didn’t know what they were. Thanks, Alex, for saving me the effort of figuring out what I photographed here.

I can’t make out what it has captured, a beetle maybe?

Can you make heads or tails of this (that’s a hint)? Leave a comment with your guess.

Identification Challenge #1 Reveal

Posted on September 8, 2010 by Troy Bartlett

Maybe I made the first identification challenge too hard. No one even ventured a guess in the comments in the two months since I posted it. Here’s the image again:

Here’s another view that might make it a bit easier.

This is the egg mass of an eastern tent caterpillar. Next spring, I should see the distinctive webbing on the cherry tree in my backyard where I found this. There’s hundreds of eggs here, but last time I checked it, it was looking a bit worse for wear. The varnish so clearly visible here has worn and chunks of the mass are missing. Perhaps some eggs were parasitized and the parasites have since exited. read more
