Study Notes

Fireflies use bioluminescence to communicate

Fireflies use bioluminescence to communicate with each other through light signals.
They have light-emitting lanterns on their abdomens, flashing specific patterns.
Abscondita terminalis males use multi-pulse flashes from two lanterns to attract females.
Females of the same species attract mates with single-pulse flashes from one lantern.

Orb-weaving spiders manipulate firefly signals to lure prey

Araneus ventricosus orb-weaving spiders manipulate firefly signals for prey.
When a male firefly is trapped in the spider's web, the spider changes the firefly's flashing patterns to mimic female firefly signals.
This deception lures unsuspecting male fireflies, increasing the spider's prey.
Spiders specifically trap male fireflies, as they are more attracted to the fake female signals.
Spiders wrap male fireflies in a light layer of silk, keeping their light signals visible.
The manipulated fireflies are kept alive longer, emitting single flashes as long as the spider is nearby.
The spiders' venom likely disrupts the firefly's oxygen supply, changing their light patterns. They likely target soft body parts, not the light organs.
Removing the firefly from the web allows them to return to their normal flashing pattern.
