This individual was interesting--sort of--because it seemed to violate a key field mark I'd deduced a while back. Normally, I distinguish Oak Leafroller from the similar female Fruit Tree Leafroller because the former has a "blonde (pale buff) thorax" instead of mostly brown. This moth violates that criterion, except that I noticed the thorax is very worn--almost scaleless--which gives a view of the thorax surface under the scales which is ruddy brown. It's the *scaling* on fresh individuals which is blonde, not the thorax body itself. So caution is advised on using that mark.
I caught a photo of this male Oak Leafroller just as it was about to take off, revealing the brownish HWs, as opposed to the gray HWs of the look-alike Fruit-tree Leafroller. Compare on MPG:
Both species have been flying in the Austin area in recent weeks.
Discover Life site lead me to Genus Archips. Searching iNat helped to ID species.
