The species found in Michigan are:
U. cornuta
U. purpurea
U. geminiscapa
U. minor
U. ochroleuca
U. intermedia
U. macrorhiza
U. gibba
Only the first is a true terrestrial. U.gibba is at home growing in wet muck,
but is not a true terrestrial. By the way, your first message did get through,
I was just too lazy to answer it.
Last night the missus and I were watching a show about some 80+ year old
guy that does macrophotography filming of bugs and aquatic insect larvae et.
cetera he'd find in pond water. Bridgett was very tolerant and never complained
as, every few minutes, I'd exclaim---that's a Utric in the background!
Looked like probably U.minor or ochroleuca, but you really couldn't tell
much...
