The Chemical Language of Black Widows: Pheromones and Deception in Spider Silk

Whimsical Wavelengths - A Science Podcast by Jeffrey Mark Zurek - PhD, PGeo, Geophysicist Volcanologist Science Communicator

Episode notes

The Western Black Widow (Latrodectus hesperus) is a master of invisible chemistry. 2026 Science Podcast of the Year winner Dr. Jeffrey Zurek joins Dr. Andy Fisher (Greifswald University) to untangle the chemical love letters hidden in spider silk.

We explore how "virtually blind" predators use smell & electrostatic charges to communicate. Discover the "stinky cheese" pheromone, why males destroy female webs during courtship, and the scandalous truth about "cheating" widows who lie about their age and fitness to attract a mate.
