Brunch.

Arizona mantis (Stagmomantis limbata) devouring a live, unidentified cicada, Sierra Vista, Arizona. This was taken during my morning walk today.

The annual cicadas are at the peak of this year’s emergence. Last night I measured their pulsating song at levels between 90 and 110 decibels, which is in the range of chain saws and low-flying jet planes. During the day only a few cicadas sing at once, but in the last hours before nightfall everyone wants to join in. It doesn’t last long, only an hour of so each evening, but while it lasts it is the sound of insanity.
