One of the many unusual cryptic katydids we encountered in Cocobolo Reserve in Panama.
Common tree cricket, Oecanthus sp., from the Timucuan Preserve in Jacksonville, Florida. This is likely the genus of tree crickets responsible for Dolbear's Law - that is, the equation showing that ambient temperature can be reliably calculated by how frequently a cricket chirps. Try it for yourself: the next time you hear a cricket chirping, count how many chirps you hear in 15 seconds and add 40 to get Fahrenheit (for our Celsius friends, count how many you hear in 8 seconds and add 5) - it should be pretty close!
Meadow katydid (Conocephalinae: Conocephalini) from Iowa.
