Thank you for the detailed information, I really appreciate it. I am hopeful in regards to encountering this species. If everything goes ok, I will be returning to Arizona the first week of July. It seems like a long way to go from Tennessee, but I also plan on collecting several other local species. I have included a living photo of Asterocampa clyton. Although they fly at approximately the same time as A. celtis, they are not nearly as numerous, generally speaking. Tom
One of the species you mentioned (Asterocampa idyja) has eluded me. I wonder where would be a good place to look, and at what time of year. I am planning another trip to do some photography, and collecting. Is A. idyja a regular stray, or could there possibly be some local breeding occurring in the Southern Arizona area? I assume they also rear on Hackberry trees like other American Emperors. Below is a "borrowed" photo of this species. Credit should be given to Jerome Albre and Oscar Dorado-(photographers). Tom
I don't think that this species occurs regularly in the US. It can be taken commonly (in fermenting fruit traps) in the Yucatan and northern Belize - always in fairly mature forest. The host - a species of Celtis - is fairly common in disturbed areas - but I have never found this butterfly in those areas where the trees are young and obvious. Just in the more intact forests where the trees are mature (and difficult to pick out amoung the taller trees).

Rutowski conducted a lot of detailed work on Asterocampa and he recorded his collection/study sites in all of his publications. If you combine all of the comments, the details of the sites are noted as follows:
In the upper Sonoran Desert of Arizona, known as Blue Point and Round Valley (2000).
Round Valley: (111.5°N, 33.8°W), East of State Route 87 (Beeline Highway) where the highway crosses Sycamore Creek, South of Sunflower. Arizona.
Blue Point (): (33°48’N, 111°29’W), In a flood plain of the Salt River in Sycamore Creek, North of the Bush Highway and Northeast of Mesa, Arizona.
Austin’s (1977): early behavioral studies of Asterocampa (on which Rutowski subsequently based some of his later work), noted his study area as being on the “Western slope of the Santa Rita Mountains, CA. 10Km SE of Sahuarita, at an elevation of 1150M”.
Langlois (1964), who although reported quite a comprehensive early ‘life-history’ of Asterocampa, simply noted his study area as being conducted (not very accurately) "midway between Minnesota and Virginia"!
For those of you who are interested, most of Rutowski’s publications can be downloaded directly from his publication list, which can be found at the following URL:
