Close examination may suggest the reason for the name, however, "Monkey Slugs" is the name given to the "Hag Moth Caterpillar" and getting slugged would probably feel a lot better than what you would get from brushing up against this "monkey."

Hag Moth Caterpillars can be found late summer through early fall and seem to prefer but are not limited to oak, hickory, ash and birch trees for forage.

Interesting critter, Ken!
I had not seen these before. Google provides lots of links to more information and other pictures that confirm the ID of this distinctive caterpillar. What surprises me, though, is that just looking at these pictures I would have guessed that this caterpillar is pretty large, maybe like a wooly bear (which does not sting) or even a Sheep Moth (which does) . But according to http://www.ag.auburn.edu/enpl/bulletins ... pillar.htm,
How big is the one in your pictures?

PS. The photos of a Sheep Moth larva linked above show only part of the caterpillar. To see lots of photos of the whole thing and its close relative the Buck Moth, Google Hemileuca caterpillar.

That makes it really quite a small beast, even full grown.The full-grown caterpillar is brown, hairy, and about 5/8 inch long.

Thanks Rik
About that which is stated by the web sites, 5/8" The leaf that it is on is around one inch maybe a little less than one inch. Wish I could tell you the shrubs name but I have no idea what it is but it was not on one of the common places listed for this particular caterpillar, most things never are as reputed to be when you stumble across them. I found this caterpillar back around mid-September and it was in a shaded area. I have seen them before, not very often of course but I cannot recall whether they were in the shade or in the sun.How big is the one in your pictures?
Thanks Rik
