Trechaleid Spider with Young
The first thing I photographed after arriving in Caraça Natural Park was this hunting spider, found wandering in an unpaved parking area.
Trechaleid Spider with Young | January 25, 2010 | Caraça Natural Park, Minas Gerais, Brazil
Up until I started preparing to write this post, I figured this was a wolf spider. After reading to learn more about the parenting behavior shown here, I’m now convinced it is instead a species in the family Trechaleidae. What first tipped me off was a similar photograph in this little book:
[book:0060849746]
Several identifying characteristics are mentioned for the particular species pictured. After some online searching, most appear to be shared by other species of the family.

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.

White-marked Tussock Moth
I often encounter the easily recognized White-marked Tussock moth, Orgyia leucostigma. I found this one feeding on maple at the end of May in my front yard.
May 31, 2010 | Twelvestones, Roswell, GA, USA | ~30mm
I grabbed it for some closeup shots and to attempt to rear it.

It must have been a final instar, because it pupated just five days later. It spun the cocoon at the top of a container, but I carefully removed it to take some photos.

A flightless female emerged ten days later.
It's a female! | June 16, 2010 | ~15mm

Females cling to the cocoon until mated. That night, I carefully pinned the cocoon with her on it to a post on my deck. When I checked an hour later, mating was already in progress. The male that found her was rough looking, having lost many wing scales.
