Unknown Caterpillars in NJ - Hemileuca maia

Unknown Caterpillars in NJ - Hemileuca maia
Webb's Mill Bog, Ocean County, New Jersey, USA
May 27, 2007
Size: 1 in.
Found in the Pine Barrens in NJ. I think the tree is Black Jack Oak. These may be Gypsy Moths, but I'm hoping for something different.

Moved from Hemileuca.

based on location
and on hostplant and appearance, Hemileuca maia would seem the most likely.

Difficult to see the spines clearly,
but we think we do see the needle spines of the Buck Moth, Hemileuca, which would feed in aggregations on oak! Check in the guide here

 
Totally.
What do y'all think of H. lucina?

Whatever they are, they are quite young, but on some of them you can see the dark reddish orange coloration of the spines.
