Male Height Zone:

Low (0-3 ft), Moderate (3-8 ft)

Flash Location:

Flashing was done predominately 3 feet or lower but was seen higher when moving quickly through locations or in areas where there was a taller tree cover. Most of the flashing was done in or around vegetation near the bank edge.

Male Flash Behavior:

Actively moving through areas. They seemed to flash more in the same general area.

Female Flash Behavior:

None recognized but I did see what I thought might be dim lights near the ground. The bank was steep and not sure the depth of the pond in front of it so I didn’t get a good opportunity to observe this behavior.
