Abandoned Hornet Nest over the Chattahoochee River in Fall

Posted on October 14, 2012 by Troy Bartlett

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.

Mating Treehoppers

~4mm body | September 29, 2012 | Roswell, Ga, USA

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.

2012 International Rock Flipping Day

Posted on September 10, 2012 by Troy Bartlett

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. read more

Black-Dotted Ruddy / Holly Looper

Posted on July 23, 2012 by Troy Bartlett

Being National Moth Week, I have every excuse to post about one of my favorite subjects. Admittedly, I get more excited about caterpillars, but I enjoy seeing the moths that most of them become.

Back at the end of April, I was distracted by something while going to check the mailbox. Actually, I’m often distracted any time I venture into my yard, but that’s kind of the point of having one for me. Anyway, some large hollies form a hedge along part of my driveway. I spotted a caterpillar dropping from from the holly to the ivy beneath it. I grabbed it for a closer look and started scanning the holly for others. I quickly found another one and brought them inside for rearing. Less than a month later, I was rewarded with a Black-Dotted Ruddy, Ilecta intractata. read more

Checkered-Fringe Prominent Rearing

Posted on July 4, 2012 by Troy Bartlett

30mm | 29 October 2011 | Suwanee, GA, USA

This was one of the last caterpillars I collected last year for rearing. I generally stop looking around the end of October.

This particular caterpillar is fairly distinct and easily recognized as Schizura ipomoeae. The stripes on the head capsule are diagnostic.

Head on view

The adult on the other hand is more difficult to recognize, I think. I’d have probably given up identifying it if I didn’t already know what it was based on the caterpillar. This particular one emerged in early May.

You might have noticed I haven’t posted anything in awhile. I get a lot of enjoyment from posting here, and I remain committed to doing so whenever possible. Lately it just hasn’t been a priority for many reasons. Hopefully, I’ll now be able to get back to posting more regularly. read more

Poison Ivy Caterpillar / Dimorphic Macalla Moth

Posted on May 20, 2012 by Troy Bartlett

For many years I’ve noticed colorful little caterpillars that live individually in silken retreats on the surface of leaves of poison ivy. At a recent BugGuide gathering, a photo of one of these caterpillars was shown and I realized we still didn’t know what these were. I resolved then to rear a few to try and arrive at an identification. There’s plenty of poison ivy near my home, so I didn’t anticipate much trouble finding a few.

Here’s the first one I found. The white area just behind the head is atypical. The caterpillar is smaller than usual, so it might be an early instar. It could also represent some sort of injury. read more

Tapinoma Ant Observations

Posted on May 2, 2012 by Troy Bartlett

April 13, 2012 | Twelvestones, Roswell, GA, USA

For several days I had noticed ants racing along the bricks at the base of one of my garage doors. I finally took a closer look to see what could be keeping them so busy for so long. They were streaming between a hole in my house and somewhere out in the front yard. I tried following, but these ants are tiny, only a few millimeters long. I quickly lost them in some pine straw.

Moving out

Turns out they were moving out of my house. The ones heading toward the yard were carrying eggs, larvae, and pupae. As I watched them though, I noticed something else leaving with them that didn’t look quite right. read more

Leafrolling Mystery Caterpillar

Posted on April 29, 2012 by Troy Bartlett

20mm | April 5, 2012 | Twelvestones, Roswell, GA, USA

Earlier this month I was checking for anything interesting in my backyard when I came across this caterpillar in a rolled up leaf on viburnum. I decided to try and rear it to get an identification.

It turns out it was a final instar because it pupated beneath its leaf within a week, sometime around the 9th.

I removed the pupa from its webbing for some cleaner shots.

I checked daily for the adult, but sadly it eclosed while I was away on vacation, sometime around the 20th give or take a few days. When I got back I found a dead and beat up adult. I prefer live images of a fresh adult that I can release later, but I’ll take what I can get here I guess. read more

Easter Flowers

Posted on April 8, 2012 by Troy Bartlett

For Easter, I thought I’d post photos of some Pink Lady’s Slippers. These were all taken at a local nature center almost a year ago. This orchid is generally difficult to find, but abundant where conditions permit.

Identification Challenge #14 Reveal: Arched Hooktip

Posted on April 7, 2012 by Troy Bartlett

27mm wide | March 24, 2012 | Twelvestones, Roswell, GA, USA

No one commented on the latest identification challenge. Despite showing just the tip of the forewing, the image provided showed the distinctive feature of a subfamily of moths commonly called hooktip moths. If you got that far, it’s a pretty simple process of elimination since there are only a handful of North American species, each one easily distinguished from the other. This species is the Arched Hooktip, Drepana arcuata.

This individual appears to be a male, based on the widely bipectinate antennae. read more
