August was called the “Sturgeon Moon” by fishing tribes because the sturgeon was easier to catch in late summer. I call this month “Katydid Moon” because the katydids start up their nighttime chorus. This year I first noticed their sing-song stridulation the night after the August full moon.
Male katydids rub their forewings together to produce a chirping sound to serenade females. Like crickets, calling rates among katydids varies with the temperature, so you can get figure out the nighttime temperature by solving the equation T=(C+161)/3, with T being the Temperature and C the number of calls per minute.
