Observation Notes:

.85 mm long. Firefly was flashing. Unfortunately I got my voice recordings of flash patterns I observed mixed up so I can't be sure which flash pattern this firefly exhibited--hence, I had to select non-flashing. (However, I was very excited because I may be wrong, but I THINK I observed Loopy 5s. I could not catch one because I wasn't wearing waders, but the display was amazing. I will go back another night soon and try to catch one.)
