Caterpillars have far less bacteria and fungi inhabiting their gut than other animals and the microbes that inside them seem to lack any identifiable role, aside from occasionally causing disease. (2017-08-22)
Global warming may cause songbirds to avoid certain foods
In another example of the far-reaching impact of global warming, a URI student found evidence that suggests some songbirds may avoid eating insects that consume leaves exposed to high levels of carbon dioxide. (2004-01-26)
Want to avoid predators? Head to the poles

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.

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

#457 Trowel Blazing
This week we look at some of the lesser known historical figures and current public perception of anthropology, archaeology, and other fields that end in "ology". Rebecca Wragg Sykes, an archaeologist, writer, and co-founder of the TrowelBlazers, tells us about the Raising Horizons project and how their team is trying to shine the spotlight on the forgotten historical women of archaeological, geological, and palaeontological science. And Kristina Killgrove, assistant professor of anthropology at the University of West Florida and science writer, talks about the public perception of the fields of anthropology and archeology, and how those science are represented -...
