Moved from Orgyia.

Moved from Gypsy Moth. Changing our mind back again. Can't find any images of the Gypsy that don't have paired dorsal warts. This is a young Orgyia, just as we first thought. Sorry to have led you astray.

Moved from Orgyiini.

We were thown off by the bright yellow patches,
but now that we look at this again we realize that it has to be a Gypsy moth caterpillar. We did some searching on the internet, and there are bright yellow color forms of Gypsy caterpillars. Sorry for the false first lead. This color pattern is not present on BugGuide yet, so this will be a good addition to the guide.

Can Confirm Gypsy Moths in NL
The Canadian Biodiversity Information Facility has a pretty comprehensive catalogue of Newfoundland Noctuoidea (and Geometroidea).  The only species listed under Tribe Lymantriini is Leucoma salicis (Linnaeus, 1758).  There is no entry for Gypsy Moths.  There are six entries for Tribe Orgyiini.  I think the absence of gypsy moths from the list for Newfoundland means that Lymantria dispar is only a recently introduced species here.  This is supported by the Gypsy Moth survey - Newfoundland and Labrador - 2005 that was conducted by the Canadian Food Inspection Agency.  Three males were captured during that survey in 2 traps in St. John's, which is near where I took these photos.  Probably in the four years since the survey the Gypsy Moth population has increased a lot.

Anyway, that is a long-winded way of saying that I can confirm that Gypsy Moths live in my area albiet they are a recently introduced species.

Moved from ID Request.

Looks like it might be
a young Orgyia, but we don't know which one, sorry.
