Updated Late Dates 2011

The mild November weather allowed us to check on a special species in Michigan. Great Spreadwing (Archilestes grandis) has only been found in Livonia through the years. Julie saw individuals again a month or so ago, and had noted goldfish swimming in one of the small pools of the creek. (this may not bode well for the odonata species).

On November 6, we waited until the frost thawed and then headed to THE location. Within a minute I found a male Eastern Forktail (Ischnura verticalis) which marks a new late date.


Julie noted that she now saw a bluegill in the same pool that had goldfish previously, and the location where the A. grandis were easiest to find in past years. (uh oh) I walked further down the creek towards I-275 between the newer buildings. In the first sunlit, sheltered location I flushed a coupled pair of Great Spreadwings! Soon after I saw a solo male and either the same or another coupled pair. This marks the new late date for Michigan by 1 day.


These may be the last species the two of us see in Michigan this season, barring Autumn Meadowhawks (Sympetrum vicinum).

Today, 11/12/11, I observed a single male Great Spreadwing (Archilestes grandis) at this spot. A new late date again!
