Fauna and other natural things

[apl68]

The 13-year cicada emergence is upon us!  The 17-year cicadas mostly live farther north, so we don't face the rare double-emergence that has been in the media so much. 

The constant drone keeps vaguely reminding me of science fiction I saw on TV growing up.  Somebody must have used recordings of cicadas as a stock otherworldly sound effect.
