Praise the LORD for access to all types of information ..... we would never have room in our homes for the research books we would have to keep to find these things when we are searching.......and how about updating all of those research manuals? Thank the LORD for the internet !
Having said that, I googled "brown caterpillar with eyespots", and found him (after several other wrong searches)..........here he is.
It turns out that he is the caterpillar that becomes the yellow butterflies that we've been seeing so many of around here recently.......the Eastern Tiger Swallowtail.
I had never seen one of these little worms, but I'll probably be seeing them everywhere, now that I'm aware of them.......you know how THAT goes !
