    Aziza Cooper sends photographs of winter moths Operophtera sp. from  Goldstream Park, January 21.  Now all we have to do is to determine which species.  The first is, to me (writes Jeremy Tatum), a typical O. occidentalis.   The remaining three don’t look typical any of them (not that any of these variable moths have a “typical” form!), but I don’t see any occdentalis in any of these three, and they certainly aren’t danbyi, so I’m going to label them probably  O. brumata.

[Thinking sotto voce: I wonder if all occidentalis have tawny abdomens.  That would simplify identification if they do.]
