This is an interesting record! This was likely a firefly in the genus Pyractomena, as the flashing species known from Alberta are in that genus, and they are often found in marshy areas.
Thanks for the info! Seems like every other year we are lucky enough to catch a glimpse of these in the river valley around the park
