How stick insects honed friction to grip without sticking
When they're not hanging upside down, stick insects don't need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort required to 'unstick' again with every step.
The final nail in the Jurassic Park coffin: Next generation sequencing reveals absence of DNA in sub-fossilized insects
It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the ...

RoboBees: Robotic insects make first controlled flight (w/ video)
In the very early hours of the morning, in a Harvard robotics laboratory last summer, an insect took flight. Half the size of a paperclip, weighing less than a tenth of a gram, it leapt a few inches, hovered ...
Scientists reveal global patterns of specialized feeding in insect herbivores
Insects are picky eaters, and not the voracious eat-everything-in-sight bingers that devour all the plants in your garden.
Arthropod 'family tree' gets bigger through evolution studies
Would you be just as comfortable nibbling on a cricket or cockroach as you would be eating a crab?
Picking up on the smell of evolution
UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
Researchers identify natural plant compounds that work against insects
Each year millions of deaths result from diseases transmitted by insects. Insects are also responsible for major economic losses, worth billions of dollars annually, by damaging crops and stored agricultural products.
Transgenic crops: Multiple toxins not a panacea for pest control
Strategies for delaying insect resistance to transgenic crops rely on assumptions that often are overly optimistic, a new study led by UA scientists shows. Published as an advance online publication by the ...
Picture this—biosecurity seen from the inside
When plants come under attack internal alarm bells ring and their defence mechanisms swing into action - and it happens in the space of just a few minutes. Now, for the first time, plant scientists - including ...
Pitcher plants 'switch off' traps to capture more ants
Insect-eating pitcher plants temporarily 'switch off' their traps in order to lure more prey into danger, new research from the University of Bristol, UK, and the University of Cambridge, UK, has found.
Study sheds light on chemicals that insects use to communicate and survive
Most insects are covered with a thin layer of hydrocarbon molecules as a waterproofing barrier. Embedded in this layer are compounds that the insects use as chemical signals for a wide variety of functions ...
