It appears that you missed the key word "form" - this is something that happens during chrysalis from a larvae to an adult. Not that a fully formed adult can't fly in colder temps. And of course, there are always exceptions.
You also should try reading the PDF from Cigar Magazine that you linked to before you attempt to wave it around.
Look at page 3 under "Temperature is Key"  |
You can see the previous discussion here:

But that aside, you've covered yourself by saying, there are always exceptions. And that might be what's going on. The life cycle points out
"Pupation takes from one to three weeks and after emerging the adults live from one to four weeks." So there could be some overlap but middle of Oct. temps were still below 71.5.
I did find another article though that shows if less than 18C (64.4F) temps are maintained the reproductive cycle can be blocked.

The pdf I linked to was simply a nice write-up on beetles in general. I put the disclaimer that it's from cigar magazine, so take it for what it's worth. The author does refer to names but there are no specific sources cited for the material he is referencing. I had to look up through journals what he was referencing. Mueller (whom I assume is David K Mueller of insectslimited) is trying to promote his own line of products. So again, take that for what you will. It also seemed that T.G was quoting from that article, so I posted the link.
I still cannot find Mueller's research that shows that wing formation stops at 70F. Unless this was some sort of personal conversation between the article's author and Mueller. in which case I won't find it. I did however, find that at 20C (68F) eggs still hatched. In my own geeky way I would like to read the article on wing development.
This is most likely the journal that will have that information if any of them do:
http://journals.cambridge.org/action...ne&aid=2606196
Any of you college kids have access to this journal??
