Moth - Papaipema insulidens

Moth - Papaipema insulidens
Barkhamsted, Litchfield County, Connecticut, USA
Is this an Indigo Stem Borer or maybe Northern Burdock Borer? Any help is appreciated.

Moved from Umbellifer Borer.

Papaipema birdi was synonymized with P. insulidens in Lafontaine & Schmidt (2015) (1).

Moved from Borer Moths.

The pain of Papaipemas. This
The pain of Papaipemas. This is another tough group, most of which are not pictured in Covell. Burdock borer is possible but consider this; the spots nearest the head are cream colored not white as in your pic. This "supposedly" eliminates many of the choices. I say this because I've seen 2 photos of P. birdi (9486) that match yours, but the literature says that area is cream not white. Are you as confused as I am? The only other match I have seen is P. marginidens and possibly P. eryngii. This is a group for experts.

Thanks Dennis. I went in the MPG and found Jim Wiker's Papaipema Moths page. His P. eryngii sure looks like a match. Before I go putting a name on it, we'll wait for a Papai expert to confirm or deny. Nice tip about the cream colored ones. They call this one a Rattlesnake-master Moth. Well, we have Timber Rattlers up here. If the name has much to do with it.

The name comes from the foodp
The name comes from the foodplant called rattlesnake master. Literature states that this can not be the only food source because that plant is restricted to prairie like settings, and the moth is collected in many places that plant is not found. Probably a poor choice for a common name.
