We published a paper
about refinding Tiger Spiketail (Cordulegaster erronea
) in the Great Lakes Lakes Entomologist (50(1-2):1-5 · January 2017
) a couple years ago. I thought it would be worthwhile to note this paper given similar habitats that may be occupied by Tiger Spiketail and Gray Petaltail (T. thoreyi
) that we found at Fort Custer Training Center in Kalamazoo County, Michigan.
|Title and Abstract. Note: both Julie Craves and Mark O'Brien have retired from their positions posted|
Individuals were initially found on July 3, 2016, and multiple individuals were found in June-July-2017.

In 2017, I searched habitats near the two-track in order to find potential breeding site(s). The most promising location was south of the area with a seep flowing from the hillside and forming a rivulet. This traveled a couple hundred meters before ending in a marshy / fen area. Further downstream is a large fen area.
