This little monarch caterpillar is growing by leaps and bounds. They go through five instars ( or stages between moults) before becoming a chrysalis.Eating, frassing ( pooping) and shedding is his/her job right now.Milkweed is the ONLY food.( besides the shed skin,which makes a tasty snack)
I also have a facebook page for my Waystation.
