Some make nests inside seashells, others tote bubbles of air on their backs. The spiders that went back to water evolved lots of slick survival strategies.
The blood-sucking insects now show up in two varieties and are resistant to many pesticides. New eradication strategies include fungal spores and nasty human odors.
OPINION: International commerce and travel bring ecological destruction to the world’s most cherished natural places. We need to do more to stop the assault.
Social insects and humans share the trait of divvying up tasks, as do some fish. Researchers find that it emerges naturally, and it often doesn’t take a boss to keep things in order.
Researchers are rediscovering the forgotten legacy of a pioneering Black scientist who conducted trailblazing research on the cognitive traits of bees, spiders and more
These stealthy survival tactics could teach us how to curb the widespread use of chemical pesticides in agriculture. But first, researchers must learn how seemingly helpless flora deploy this masterful strategy.
Bt crops keep many agricultural pests at bay and have drastically reduced the use of pesticides. But scientists warn that these valuable tools are in jeopardy due to overuse and abuse.
How do animal populations respond to climate change? After studying the same butterfly and its habitats for decades, two biologists explain that it’s complicated — but endlessly intriguing.
The world’s natural history collections hold billions of biological specimens, many of which still contain DNA. Scientists exploring these genetic repositories are gaining new, historical perspectives on how animals evolve.
Carnivorous plants fascinate as much now as when their gruesome diet was first discovered. Molecular biology is helping botanists trace the origins of their predatory ways.
The complex interplay of ticks, their habitats and hosts — along with changes in land use and climate — may be enabling the spread of the pathogens they carry
Social insects disobey evolutionary principles that say creatures invest in body maintenance or reproduction — not both. Scientists want to know how the creatures do it.
Millions of years of coevolution have given the insects a bag of tricks to escape their predators — from signal-jamming and decoys to acoustic camouflage
Fifty years ago, Geoff Parker’s pioneering scholarship on “sperm competition” in insects was broadly overlooked. Since those days, hundreds of studies in many animals have confirmed the importance of what he discovered while watching flies mate around cow pats.
Some spiders pair puny males with gigantic females, making mating both tricky and dangerous. Why and how such mismatches evolved remains curiously enigmatic.
Dozens of times over the eons, rove beetles have made complex, independent adaptations to live inside the nests of ants — the phenomenon of convergent evolution. Biologists want to know if this shows patterns at work in natural selection.
By engineering mutations into fruit flies, scientists reconstructed how the butterflies may have evolved resistance to the toxins found in milkweed, allowing their caterpillars to feast on the plant
Evolution made insect ears many times over, resulting in a dazzling variety of forms found in spots all over the body. Biologists are digging deep into some of those ears to figure out how and why they came to be.
COMIC: The feisty orange-black butterfly uses a toolbox of biological tricks to find its way down to Mexico for winter and flap north again in spring. Here’s how scientists figured out those tricks — and what they don’t yet understand.
