This photo taken June 4, 2015 shows the color variability in Tulip Tree Beauties. The moth in the middle is the melanic form "carbonaria" of this species. It's the first time I've seen one so dark. The one up top seems to be somewhere between the two below it, colorwise.

This, by the way, is how they landed on the sheet! (I did flick a couple of little moths out of the frame, though...)
Cloaked Marvel - "White Form". 
Chytonix palliatricula

As with the previous entry below, this one adds a new form to a moth already on this site. Never saw this before last night. Those bold white patches jumped right out at me.
False/Crocus Geometer
Xanthotype urticaria/sospeta

What the...? I can't believe I've never added this one to the site. They're fairly common and I always just assumed it made it here over in the last dozen or so years. But nope...

Anyway, this a butterfly-y kind of a moth, often confused by people as the former. Always check the antennae! There is an actual, bonafide, non-false, Crocus Geometer, but it generally lacks the heavy brown markings this one shows. Apparently, though, those morphological differences aren't enough to distinguish between to two species.
