I've put 174 alterna into a MS excel database. I haven't yet figured out how to do calculations with it so can't give averages, but here is a bit of data
Low temp: 68
High temp: 92 (air temps)
median temp: 82
Earliest: 9:52 PM
Latest: 4:38 AM
number caught before midnight: 118
after midnight: 55
This is not my entire collecting notes. Some I didn't put down data for and I think I missed a year or two when entering. It was not a fun job.
