Orb-Weaving Spiders Manipulate Firefly Signals to Trap More Prey

Researchers reveal how Araneus ventricosus spiders exploit the bioluminescent signals of male fireflies to attract additional victims.

Male fireflies trapped in the spider's web are induced to emit female-like flashing signals.
This deceptive signaling lures more male fireflies into the web, increasing the spider's catch rate.
Field experiments confirmed that webs with spiders present captured significantly more fireflies.
The exact mechanism of how spiders alter firefly signals remains unknown, though venom or bites are suspected.
The study suggests broader implications for understanding predator-prey communication strategies in nature.
