What appears to be a flower here is actually a group of caterpillars working their way down a sapling trunk.

They look like they could do a decent job sharpening a pencil, about the same width as this tree(?) trunk.

Despite the black background, this was taken a few hours before sunset. At the time there was probably a few feet of the trunk left. I marked the location and returned after dark. I found no trace of the trunk or the caterpillars. They apparently ate the whole tree.

I know there are defoliating caterpillars. I know there are wood boring caterpillars. I never imagined there are caterpillars that consume an entire tree though. That’s assuming they eat leaves, which I didn’t observe.

Long-legged Fly with Prey

It wasn’t until I reviewed this shot on my camera and saw the prey, that I realized long-legged flies (family Dolichopodidae) are predatory.

Abandoned Hornet Nest over the Chattahoochee River in Fall

In Fall, bald-faced hornets enter the autumn of their lives. Surviving adults, no longer responsible for providing masticated prey for the colony’s growing young, enter into a retirement of sorts. They abandon their nest and spend their last days, up until the first frost, feeding on nectar. Only mated queens survive to found new colonies the following year.

 

 

Highlands Tiger Beetle

I wasn’t properly excited when I photographed this tiger beetle. I now know this species, Cicindela highlandensis, is a somewhat rare endemic species. There were no shortage of them at this particular spot though.

Honestly, I ignored them at first, not being sure I wanted to invest the effort required to get some good shots. Eventually, I had already prostrated myself for some shots of other subjects, so I figured what the heck. I’ll admit I was also somewhat motivated by a desire to share some tiger beetle shots here for frequent commenter Ted C. MacRae to see. 🙂

Head on view, Ted’s trademark shot I think.

I like those single small hairs that stick up from above each eye.

These really are relatively small tiger beetles. I’m guessing that doesn’t stop them from tangling with big prey though. Looks like this one perhaps bit off more than it could chew, since it seems to be missing some antennal segments.

Their dark color allows them to blend in quite well with all the other debris scattered about their sandy habitat. You don’t really notice them until they take flight.

I’m going to follow Ted’s lead and not reveal here the exact location where these were found. Looking at the timestamps of my images, I spent less than five minutes chasing this one beetle. If I go back, you can be sure I’ll spend more time photographing this species.

Mating Treehoppers

These mating treehoppers (Acutalis brunnea) picked a good place to get together, at least from a photographer’s perspective. I like the composition of this full frame image, but there’s so many different ways I could crop it.

Here’s a closer look at the pair.

I’ve stared at the full size image, but I can’t decide which one is male and which one is female.

 

BugShot 2012: Wolf Spiders

September 26th, 2012 - 9:55 PM | Filed under Featured Photos | 1 Comment

I enjoyed BugShot 2012, but didn’t take as much advantage of the setting as I’d hoped. By the time I got to Archbold Biological Station, I was coming down with what turned out to be an upper respiratory infection that would last for several weeks. At the end of each day I mostly just wanted to sleep. Not wanting to totally waste the opportunity, I did venture out for several hours on the final night.

Wolf spiders were everywhere and were easily found by the reflections of their eyes from my headlamp. This lighter colored one was my favorite.

That initial shot was more for documentation purposes to aid in potential identification later. With that out of the way,  I decided to get closer…

Having been stationary for awhile, my headlamp started attracting insects. The wolf spider capitalized on the situation, yielding my favorite shot.

To get these shots I ended up chasing it around quite a bit. Each time, I’d try to carefully remove as much debris as possible from around it for a cleaner background. I got rid of the bigger bits, but there was still lots of smaller stuff left. I suppose controlling that sort of thing is one advantage of studio shots.

I ended up with a few decent shots and lots of sand all over myself and my equipment.

There were also some darker colored wolf spiders that really stood out against the white sand. When viewed amid the dry vegetation, however, they were difficult to spot.

This particular spider captured my attention in a way I hadn’t expected. When you’re shining for spiders using a headlamp, you usually see just a few reflections from their large forward facing eyes. When my lamp light shone on this one, however, I thought I’d found a walking jewel. Light reflected from all the eyes of the babies she carried on her back, as if from a multifaceted gemstone!

Red Widow with Egg Sac

While on my way to BugShot 2012, I spent several days exploring parks along the way. My favorite spot was the Nature Conservancy’s Tiger Creek Preserve for the variety of habitats its trails pass through.

Here, I was curious about some some palmetto leaves that had been sealed up. Peeling a layer of leaves away, I found a red widow guarding her egg sac.

2012 International Rock Flipping Day

September 10th, 2012 - 10:33 PM | Filed under Featured Photos | 3 Comments

Yesterday was International Rock Flipping Day. I’ve read about it in the past, but this is the first year I’m participating.

I don’t really need an excuse to flip a rock and explore what’s beneath, but the whole event certainly motivated me to get my blog posts going again. I have been busy outside of blogging, so there’s plenty of good stuff coming up, so don’t give up on me.

Yesterday was beautiful here in my area, so I already had plans to go bug hunting. Knowing I’d be looking for a rock to flip, I chose a nearby park where I knew there were lots of good candidates. Here’s the rock I settled on after being distracted by lots of other interesting critters along the way.

A stone lies on the sun-dappled floor of an eastern deciduous forest, begging to be flipped.

I carefully turned over the rock, hoping for something blogworthy. On the ground beneath, a centipede uncoiled, drawing my initial interest. Scanning the scene, I also saw a millipede and a few ants. Then, movement on the underside of the rock itself drew my attention. A harvestman in the family Cosmetidae betrayed its presence.

I’ve seen this type of harvestman before, and a photo of that one submitted to BugGuide has since been identified as belonging to the genus Vonones.

Here are some of my favorite shots of this harvestman, the only thing from that rock that I chose to photograph for the 2012 International Rock Flipping Day.

Coming over a ridge in the rock and exposing some interesting anatomy.

The harvestman shows its butt.

Having made its way around to the top of the rock, the harvestman continues its evasive maneuvers.

Tiring now from the constant corralling of the photographer, it attempts a stare-down.

The photographer having tired of the chase, the harvestman finally escapes.

 

Aruba’s Fontein Cave Art

Fontein Cave | April 23, 2012 | Arikok National Park, Aruba

Arikok National Park contains the most well known of Aruba’s caves. I visited one of them, Fontein Cave, guided by a park ranger.

Arawak indians inhabited Aruba around 1000 AD. They adorned the walls of this cave and others with petroglyphs.

At the park’s visitors center, a display suggested that the following petroglyph might be an ironclad beetle.

My guide quizzed me on a few others. I was asked about this one first.

Bzzzzt, what do you think this represents?

I guessed honeycomb. My guide smiled and vigorously nodded.

Bees were definitely on my mind though. I had just seen a bee hive in the limestone not far from the cave entrance.

As I stared at the bees coming and going, I started to wonder if I might be watching killer bees, since I was well within their range. As that thought crossed my mind, I was suddenly stung on my arm. Fighting the urge to run, I calmly walked away, without further incident.

Getting back to the cave though, my guide shone his light on another spot. Here, I had no clue what the petroglyph might represent.

Can you guess what this might be?

I’ll leave that one as a challenge of sorts. Feel free to comment with your guess. I’ll post a comment later on with what my guide told me.
