While walking around campus at my workplace in Farmington Hills, Oakland County, MI, during lunch hour on October 24, 2011, I found 3 of the last dragonfly species of the season.
3+ Familiar Bluet (Enallagma civile)
1 Common Green Darner (Anax junius)
4+ Autumn Meadowhawks (Sympetrum vicinum)
Over the following days I kept an eye out for these since the late dates for specimens was approaching.
On October 31, I was able to find a female Eastern Forktail (Ischnura verticalis) for what I believe is a new late date for a MI voucher. The previous late date in the MOS database was an individual I had on 10/07/07.
This image is of a female I found in Monroe County earlier in October:
On November 2, I found one female and one male Familiar Bluet (E. civile)! This, too, is what I believe to be the latest date for a MI voucher. The previous late date in the MOS database was an individual I had on 10/19/10. Here is the male:
Today is one of the truly nice days remaining for this year. We'll head out to look for the last possibilities of flying damsels around here.
