Caterpillar gets more from its food when predator is on the prowl
Animals that choose to eat in the presence of a predator run the risk of being eaten themselves, so they often go into a defensive mode and pay a physical penalty for the lack of nutrients. (2012-07-12)
Some caterpillers just don't want to grow up
An international project explores why it's an evolutionary advantage that only 25 percent of the caterpillars of Maculinea rebeli, a Lycaenid butterfly whose caterpillars live as parasites inside colonies of Myrmica ants, feeding on regurgitations from the nurse ants, complete development within one year. (2007-03-16)

A Bt corn variety grown widely in East Central Illinois in 1999 had no adverse effect on black swallowtail caterpillars that thrive in weeds alongside cornfields, according to both field and laboratory studies at the University of Illinois. (2000-06-05)
Parasites prevent ants from protecting coffee plants
Azteca ants are voracious predators that live on coffee plants and aggressively defend their territories. (2003-08-05)
Obesity crisis in insects? Not a problem, says expert
Ever seen a fat insect? Probably not. Dr. Spencer Behmer may have the answer why, and that could have implications for what is billed as the current human obesity epidemic. (2006-09-20)
Gypsy moth caterpillars hormonal slaves to virus gene
Gypsy moth caterpillars infected with baculovirus forfeit safety and stay in the treetops during the day because a virus gene manipulates their hormones to eat continuously and forgo molting, according to entomologists. (2011-09-08)
Technology protects cotton from caterpillar's appetite
To demonstrate tiny cotton-eating caterpillars' destructive power, Clemson University entomologist Jeremy Greene planted two cotton varieties -- one genetically modified to provide protection and one not -- in a demonstration field at the Edisto Research and Education Center in South Carolina. (2011-02-01)
Plants under attack can turn hungry caterpillars into cannibals
When does a (typically) vegetarian caterpillar become a cannibalistic caterpillar, even when there is still plenty of plant left to eat? (2017-07-10)
The very defensive caterpillar
Caterpillars are bleeding defensive! Dr. Ionannis Eleftherianos from the University of Bath, UK will speak about the discovery of a protein response system that protects caterpillars from lethal infections when pre-infected with non-pathogenic bacteria. (2005-07-12)
Insects that deter predators produce fewer offspring
Insects that frequently use their defense mechanisms to deter predators could be reducing their lifespan and numbers of offspring, researchers at the Universities of Liverpool and Glasgow have found. (2011-01-25)
Butterfly migration could be largest known
Millions of painted lady butterflies that fluttered into California's Central Valley in the last week of March could be just the advance guard of one of the largest migrations of the species on record, said Arthur Shapiro, a professor and an expert on butterflies at UC Davis. (2005-04-08)
Oaks' Defenses Help Gypsy Moth Caterpillar Fend Off Virus

Oliver Sipple
One morning, Oliver Sipple went out for a walk. A couple hours later, to his own surprise, he saved the life of the President of the United States. But in the days that followed, Sipple's split-second act of heroism turned into a rationale for making his personal life into political opportunity. What happens next makes us wonder what a moment, or a movement, or a whole society can demand of one person. And how much is too much?
