Here’s yet a different species of colorful treehopper. These too were found in association with ants.

A busy photo, but packed with natural history.

Ants Tending Treehoppers, Poorly Perhaps

I had planned to post just a single photo of this scene with ants tending treehoppers. Here we see at least two different colorful treehopper instars, with one actively molting. Ants like the one shown above tended to this small grouping of treehoppers. As I was choosing a photo to post, I noticed something strange about the treehoppers though. Do you see it too?

Look closely and you’ll see that a few nymphs have parasites. I wasn’t sure at first, so I started looking through my other photos. Sure enough, almost every one had one or more parasites. The parasites seem to prefer hiding under the wing pads and below the thorax. read more

Ants Tending Leafhoppers

These ants are tending to some treehopper nymphs. Most of the ants are busy collecting honeydew, but the one on the bottom has noticed me and is on alert. I accidentally bumped the branch after this shot and all of the ants started running around looking for something to attack. I held up a leaf for a background here so that the ants would stand out.

In this next shot, I’m assuming the white areas are either treehopper eggs or a protective covering for the eggs. One of the adult treehoppers is also visible here, a darker shade of red than the nymphs. 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.

Ant tending Caterpillar

Here’s an ant in the Formica genus tending a caterpillar in the Lycaenidae family. The ant has just taken a drop of a sugary substance produced by a gland at the rear of the caterpillar. Here’s a shot from about 10 seconds earlier where you can see the drop sitting atop the gland and the ant fast approaching.

Sugary drop produced for tending ants

I’m not sure what flowers these caterpillars are eating, but they are pretty well camouflaged settled in among the flower buds. Once I spotted the first one, I started looking for them and found quite a few wherever I spotted these flowers. read more

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
