Dinner at the Cow Patty

Remember I said in the location profile for Tupaciguara that cattle are abundant? I was driving through one of the many cattle pastures at night when I noticed that some of the fresher cow patties were being visited by moths.

I suppose this shouldn’t be too surprising. I’ve seen plenty of butterflies taking nourishment from bird droppings and other animal scat. Well, at least something is benefiting from those cattle.

Some other random thoughts:

I wondered if anyone has ever done a study on how many and what types of species come to cow patties? That might be worthy of an Ig Noble prize. read more

Some Army Ant Observations

That’s the general scene. I encountered these army ants on the side of the trail towards the end of the afternoon. The odd thing is that I didn’t see much more than what’s shown here. There were a couple of holes in the ground, outside the shot above, but roughly in the upper left and lower right. Despite some searching in the nearby vicinity, I didn’t find any other ant trails. But there were ants streaming in and out of the two holes, forming roughly two paths. The bottom path was moving to the right and the top to the left. read more

Ants Herding Treehoppers

These ants have quite effectively corralled their herd of honeydew producing treehoppers.

There’s a lot to see here if you look carefully. First, it looks like quite a few of the life stages of the treehoppers are present. There’s the dark adult in the center, an early instar in the bottom center, and the majority appear to be middle instars.

In the detail below, you can see the ant on the right has just taken a drop of honeydew and the dark adult has a drop waiting.

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

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.
