G. E. Crow
Floating on still water of ponds and river backwaters in southernmost Michigan; rare and seemingly transient in appearance from year to year.
Poorly known in Michigan and, although native to eastern North America, the first collection being as recent as 1993 makes it uncertain that it should be considered native to Michigan. However, it is admittedly very easy to overlook.
