False Robust Conehead (Neoconocephalus bivocatus)

Song of a False Robust Conehead (scroll down for explanation and additional recordings!).

insect_musicians_Neoconocephalus_bivocatus_WH__WIL0134As you might expect, the False Robust Conehead is very similar to the Robust Conehead. However, it is slightly smaller and begins singing earlier in the evening. They also have an immaculate cone. The False Robust Conehead is found in weedy fields near and far from water. Since they sing while it is still light out, it is easy to track them down and get a look at one while it is singing. They will see you coming and move to the opposite side of the grass stem as you get closer. If you remain motionless for a few minutes, he will resume singing. You can often get within a yard or so of a singing male. This can lead to great views of a singing insect.
