To the best of my knowledge, you can find L. archippus on the wing in 
parts of Arizona year-round.  Check with the state BISON report.  A 
quick web search should produce some localities.  Actually, you'll be 
dealing with L. archippus obsoleta in Arizona.  This subspecies 
occurs in the Rio Grande Drainage in western Texas and southwestern 
New Mexico (Austin 1998 in Emmel's Systematics of Western 
Butterflies).  It also occurs in the Colorado river drainage + others 
throughout southeastern CA, southern Nevada, southwestern Utand and 
southern, western and central Arizona (again, Austin 1998 etc.).  I 
mention this only to remind you that obsoleta is officially 
considered a threatened taxa.  Ecological pressures such as water 
impoundment and an invasive salt cedar have caused widespread 
population declines of this subspecies.

Well, probably more than you wanted to know but hopefully helpful. 
Just make sure you get permits if you plan to collect Obsolete's in 
the southwest.
