Cuivre River State Park

Aaron Brees stated he felt this moth could also be S. forbesi (a recently described species - 2014 - not in MPG) and he linked me to a paper on this genus.
Bruce Schuette: “Of course nothing is ever crystal clear as we have both species of Triosteum and a couple species of Fraxinus [in Cuivre River State Park]. Normally Chrissy and Andy collect in the campground [and that was the case this night] and if that was the case there are a lot of ash trees scattered around and throughout - so that would probably be the most likely. Triosteum is scattered around and I know it’s along the lakeside below the campground, but I don't know for sure of any immediately in the campground. So if that was their location I would guess the odds would be greatest for it being the Fraxinus feeder. There are definitely places to check the Triosteum itself for larva during the summer. I hope that helps some.”
Philip Koenigh: "There is no way to know which species it is for sure. The moth may have flown quite some distance. The two species should be reared from larvae and the adults pinned. A photo of the larva and the adult can be posted together."
