Good housekeeping: why do shelter-dwelling caterpillars fling their frass?
Caterpillars of the silver-spotted skipper butterfly ballistically eject their individual fecal pellets (frass) as far as 40 body lengths away from their resting places in leaf shelters. Why do these and many other shelter-dwelling caterpillars go to such great lengths to distance themselves from their waste? In a paper to appear in the April issue of Ecology Letters, M. Weiss shows that... View News Article (2003-04-08)


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. View News Article (2012-07-13)


University invention enlisted in battle against the brown-tailed moth
An environmentally friendly insect trap devised by researchers at the University of Southampton is the latest weapon in Portsmouth City Council's long-running battle to control infestations of the caterpillars of the brown-tailed moth. View News Article (1998-09-04)


Study finds that mild winters are detrimental to butterflies
The recent mild winter throughout much of the United States was a cause for celebration for many. However, butterfly aficionados shouldn't be joining in the celebration.  View News Article (2012-04-23)


Modern caterpillars feed at higher temperatures in response to climate change
Caterpillars of two species of butterflies in Colorado and California have evolved to feed rapidly at higher and at a broader range of temperatures in the past 40 years, suggesting that they are evolving quickly to cope with a hotter, more variable climate.  View News Article (2013-12-19)


Parasites trigger healthy eating in caterpillars
Some parasites trigger their own destruction by altering their hosts' behavior, researchers at The University of Arizona and Wesleyan University report in Nature. View News Article (2005-07-29)


Transgenic maize is more susceptible to aphids
The environmental consequences of transgenic crops are the focus of numerous investigations, such as the one published in the journal PloS ONE. View News Article (2007-08-30)


Insects that deter predators produce fewer offspring
Scientists studied the defenses used by caterpillars that transform into large white butterflies, called Pieris brassicae. The insects regurgitate semi-digested cabbage leaves to make them smell and taste unpleasant to predators. View News Article (2011-01-26)


Great tits can reduce caterpillar damage in apple orchards
The potential contribution of vertebrate predators to biological control in orchards has been largely overlooked to date. A few studies have shown that birds reduce numbers of pests, but data are scarce on the effects on the pattern or timing of damage. Consequently, the practical value of birds as biocontrol agents remains unclear. View News Article (2002-11-26)


Technology protects cotton from caterpillar's appetite
The furry-looking insects start their development smaller than the head of a pin, but the caterpillars soon develop an appetite for cotton as big as the crop. View News Article (2011-02-02)
