On Tuesday, August 26th, I stopped by the Great Spreadwing (A. grandis) location in Wayne County.
I was worried that the upstream construction at 7-Mile & Haggerty Road may wipe out the population of Archilestes grandis due to silt,
etc. I was pleased to find 4 females (3 tenerals) and 3 males (1 teneral) for a
new early date in Michigan.
We'll see if the development's future use of landscape chemicals and runoff impact the population. I hope they're not impacted since it's great to be able to observe such a large damselfly in the area.
