Listen: Moths Flee or Face Bats Depending on Toxicity
"About twelve thousand species of Tiger Tiger Moth Earth. Some of them swoop and dive out of harm's way when Hungary bat tries to make them a meal but other tiger moth species are more blase I say they just don't bother to flee from Hungary bats and I really just wanted to know why why the difference what factors might be influencing whether a species. She's is more or less likely to perform these. Evasive maneuvers. Wake Forest University behavioral ecologist. Nick Dowdy he says it's a matter of taste i. Some of the malls are delicious but others are toxic and tastes terrible when the airborne predators catch these unappetizing moths. They'll spit them out. Giving bring the insects a new lease on life in a field experiment dowdy and his colleague William Connor filmed health five different species of tiger. Moths responded to bat attacks. Ax and what we found. was that those species which were really toxic so when the bats captured them they almost never ate them. Those species are much more likely likely to be. What we call nonchalance species that do not perform evasive maneuvers very often on the other hand species that were really palatable? We're much more likely to perform those evasive maneuvers. Almost in a sense sort of hedging their bets because if they don't make that escape if they are captured by a bat those species these are more likely to be another factor. Is that evasive maneuvers. have their own set of risks which may be why unpalatable. Moths tend to avoid them for for example diving away from Bats Burns fuel gives the insects less time to seek out mates and could expose them to other perils such as getting stuck in water or there could be predators on the ground like mice and other mammals the study is in the Journal. Frontiers in ecology and evolution. Doughty is now trying to identify The chemical compounds responsible for making some tiger. Moths taste bad wants. Those findings are in chemical analysis of museum. Specimens could help reveal l. how rare endangered or even extinct insects have behaved around predators. Study animal behavior even without a living organism. That's pretty amazing. Other animals with conspicuous warning signals such as garishly coloured poison dart frogs and foul smelling skunks are also tone to be slow. Movers perhaps a few deadly toxic or just plain stink can pay to be"
