Why read this
Cicada song sits between anatomy and culture: sound without lungs or vocal cords, heard as music, divinity, or overwhelming seasonal force.
AI brief · Checked against source text
The main idea
Popova presents cicadas as both biological mechanisms and cultural presences: insects whose bodies produce sound without lungs or vocal cords, yet whose choruses have long seemed musical, divine, or overwhelming. The piece works by layering emergence cycles, acoustic anatomy, historical reactions, and Anna Botsford Comstock’s field-guide prose, so the sound becomes neither mere metaphor nor mere physiology.
Go a little deeper
Timing makes the spectacle mechanical and uncanny
The emergence is described as synchronized but not mystical: soil temperature and April averages are tied to when the brood begins surfacing. That pairing matters because the piece preserves two perceptions at once. Cicadas appear like a sudden underworld visitation, yet the trigger is treated as measurable, even formulaic, making wonder depend on mechanism rather than ignorance.
The instrument is the body
The key distinction is that cicadas are not making sound by friction like locusts. Their hollow abdomen, tymbals, membranes, and rapid muscle movement turn the male body into a resonant instrument. That explains why the essay’s musical language is more than ornament: the analogy to drums or mandolin is grounded in the insect’s physical structure.
Old listening changes the scale
The piece repeatedly widens the cicada from summer insect to historical companion. Greek admiration, Homeric comparison, Byron’s verse, and Comstock’s claim about unchanged instruments make the chorus feel continuous across civilizations. The effect is not simply nostalgia; it argues that attention to small creatures can carry deep cultural memory.
A case from the article
Comstock’s Lyreman
Comstock’s field observation supplies the most concrete case: a common male cicada, hidden in trees, sends out a summer trill, and when held can be felt vibrating. Turning it over reveals paired concealed cavities with membranes and muscle-driven drumheads. The example shows how the essay fuses sensory intimacy with anatomical explanation.
How the case is made
The case is made through natural-history explanation, historical literary references, and extended quotation from Anna Botsford Comstock’s 1903 insect guide.
Where the idea has limits
The evidence is lyrical and explanatory, not a full scientific treatment of cicada evolution, acoustics, or brood ecology; its strength is synthesis and close description.
A question to take away · from Digna Legi
What changes when a natural sound is understood as anatomy, seasonal signal, and inherited human symbol at once?
What the original adds
The source adds historical voices, including early colonial astonishment, Greek and Romantic literary associations, and Comstock’s detailed description of the Lyreman’s concealed sound-producing organs.
