Afflicted Dagger Moth Caterpillar - Acronicta brumosa

Afflicted Dagger Moth Caterpillar - Acronicta brumosa
Fort Bragg, Cumberland County, North Carolina, USA
September 18, 2004

brumosa ?
Wagner (1) page 323 says afflicta has one pair clubbed black dorsal setae per segment while brumosa has two pair

 
Thanks
Does it give a common name for brumosa?

 
No sorry
He doesn't even picture it. Just mentions it on the same page as Afflicted. If you're going to search the web for it and make a guide page, see what you think about a couple of Troy's images there too. Looks like they also have two pair of black setae.

 
Thanks,
I saw Troy's. I already searched the web and found no images of caterpillars. How do you feel about me created a guide page on your reference?

 
Not too unreasonable
Though we would make the guide page based on the description in Wagner. It's on the page with afflicted so he apparently thinks they look similar, but he makes the distinction of two pairs. Here's the quote if you want to use it. Wagner (1) page 323 for A. afflicta "Last instar beige to salmon with charcoal middorsal stripe and clubbed, black, dorsal setae that are about as long as segment that bears them. One pair of clubbed setae per segment....Acronicta brumosa, a species of xeric oak woodlands and barrens, has two pairs of black, clubbed dorsal setae per segment, which arise from orange pinacula." With fifty species of Acronicta east of the Mississippi, there could be even more that fit the description, but it seems brumosa is the best we can do for now. We'd say, go for it.
