Hi, my son and I recently found this(bug) on the ground outside our house. I tried to look it up online, but found nothing. It is very small and strange looking. It sticks to your finger on the bottom it looks like small hairs almost velco like. When touched it seems to shrink up a very small amount you have to watch it VERY close or it doesn’t even look like it is moving. We call it our alien bug. We brought it inside and put it into our plant container, about 6 hours later it was gone, or so we thought until we found a small brown ball in the corner. When I poked it, it opened up and the bug was inside. I took pictures of it and by morning it was in a ball again. What is this? I am so curious. What is it going to turn into when it emerges?

Hi Renee,
Your caterpillar is one of the Stinging Slug Moth Caterpillars, Isa textula.  The adult moth is brown and relatively nondescript.  You can see images of both the caterpillar and adult moth on BugGuide.
