The love and lies of
fireflies
Sara Lewis:
Biologist Sara Lewis has spent the past 20 years getting
to the bottom of the magic and wonder of fireflies. In this
charming talk, she tells us how and why the beetles
produce their silent sparks, what happens when two
fireflies have sex, and why one group of females is known
as the firefly vampire. (It's not pretty.) Find out more
astonishing facts about fireflies in Lewis' footnotes, below.
Evolutionary ecologist Sara Lewis digs deep into firefly mating rituals to
uncover a world of secret languages and strange gifts in these silent
sparks.
