I just finished watching the BBC mini-series Life in the Undergrowth staring several million invertebrates and David Attenborough. (I watched it in between the picnics, fireworks, and swimming that mostly occupies my time.) Fans of cicadas and land-dwelling invertebrates will love this show. Attenborough is the best when it comes to explaining the natural world to TV viewers.
BBC thoughtfully put the segment of the show about 17 year cicadas on YouTube.
I like the bit when he lures the male around by imitating the wing flicks of females.
You can buy it in the usual places, or rent it of course.
