There were at least 3 others on the milkweed in my yard, but they've disappeared when they were very small. So, I decided to take this little one in and keep it safe until it turns into a butterfly.
Name is Munchy BTW.
Edit: look how much it munched since I took the first pic:
Gonna be cool to see it become the butterfly.
Yeah, I'm excited. I've had these milkweed plants in my yard for years and this is the first year I've actually seen monarch caterpillars on them.
