Moth Uses Plant Toxin To Protect Mate And Off-Spring

Once he has ingested the toxin from the plant, the male is no longer tasty to his common predators, particularly spiders and bats. After gathering the poison, the moth goes in search of a female. When he finds his insect bride, they mate for nine hours. But, just before mating, the moth releases the toxin like a cloud of miniature confetti that sticks to the female. The toxin protects her while she is mating and while she lays her eggs. The female moth then passes the toxin to her eggs. The toxin deters egg-eating insects like ants and ladybugs from devouring her young. (Click on title for full story.)
