Doug, I don't know if there's a standard but I've been told to get photos of the reniform spot, along the costa out from the reniform, and near the apex. I've attached pics of one I shot today. As you can see, the scales are different in each location. They overwinter as adults so whenever it's 50 or above at around sunset, you should expect to see them. For every one I see at the lights, I'll see 5 on the bait.

I've heard that the reniform on E. vinulentais usually flat-ish on the bottom so if that spot is round, it's probably not vinulenta. I haven't examined enough to know if this holds true but others that have examined hundreds say it does. Those others are in Michigan so it's possible what they are seeing is a regional variation. I've also noticed that vinulenta has a dirtier look to it. Again, I haven't examined enough to say that holds true. > >Ken Childs >Henderson, TN >Chester County > >http://tinyurl.com/FinishFlagFarmsMoths >http://www.finishflagfarms.com > > > >>________________________________ >> From: kjchilds <kjchilds@xxxxxxxxx> >>To: TN-Moths <tn-moths@xxxxxxxxxxxxx>; "ncsc-moths@xxxxxxxxxxxxx" >><ncsc-moths@xxxxxxxxxxxxx> >>Sent: Friday, February 21, 2014 12:54 PM >>Subject: [tn-moths] Eupsilia >> >> >>I've been trying to ID the Eupsilia spp. I've been seeing here by taking >>close-up shots of their wing scales.
