THE LIVING FOREST FLOOR A fallen branch can become a nursery. A pile of leaves can shelter a whole community. Beneath our feet, leaf litter, decaying wood, and soil create a layered neighborhood where insects find food, protection, and places to grow. A woodland floor may look untidy compared with a freshly raked lawn, but … Read more
Small Creatures · Extraordinary Engineering A spider’s silk can become a trap, a shelter, or a safety line. That delicate web outside your window is more than a collection of sticky threads. It is a carefully arranged hunting structure. Yet many spiders catch every meal without building a prey-catching web at all. A web covered … Read more
SMALL CREATURES, REMARKABLE TRANSFORMATIONS A caterpillar becomes a butterfly, but a young grasshopper grows into a larger, winged version of a familiar shape. Both insects transform as they develop. They simply follow different routes to adulthood. A garden, neighborhood pond, or patch of meadow contains insects at many stages of life. Some young insects look … Read more
The Backyard Field Notebook Look at the wings. Check the mouthparts. Then follow the clues. The small visitor on your window might be a beetle, a true bug, or a fly. Learning a few visible features can turn a vague guess into a useful identification—without memorizing hundreds of species. A ladybug rests on a leaf. … Read more
In the high-stakes theater of natural selection, insects occupy a perilous ecological position: they are the primary protein source for millions of birds, reptiles, amphibians, and small mammals. Because physical speed alone is often insufficient to evade sharp-eyed predators, insects have evolved the most dazzling, deceptive, and devastating defensive repertoires in the animal kingdom. From … Read more
Every year in early June, deep within the ancient hardwood forests of the Great Smoky Mountains National Park, thousands of spectators gather in complete silence to witness one of North America’s most awe-inspiring natural phenomena: the synchronous light display of the firefly Photinus carolinus. Unlike ordinary fireflies whose flashes twinkle erratically across summer meadows, millions … Read more
In the study of evolutionary biology, few phenomena are more profound than eusociality—the evolutionary transition from solitary individualism to cooperative colonial living. Coined by entomologist E.O. Wilson, the concept of the “superorganism” views an ant colony, termite mound, or honeybee hive not merely as a collection of individual animals, but as a single, coherent biological … Read more
While humans perceive the world predominantly through vision and acoustic speech, the vast majority of the Earth’s one million insect species communicate through an invisible, silent sensory channel: chemical language. Through the synthesis and detection of semiochemicals—volatile organic molecules secreted into air currents or deposited onto substrates—insects coordinate monumental colonial tasks, attract mates across miles … Read more
As urban sprawl transforms millions of acres of wild forest and native prairie into concrete infrastructure, asphalt roadways, and manicured suburban turfgrass, a fundamental ecological question arises: can insect biodiversity survive in modern human cities? Traditional conservation models historically viewed urban centers as ecological wastelands. However, pioneering entomological field research across major American metropolitan areas—from … Read more
The arid deserts of the American Southwest—the Sonoran, Mojave, Chihuahuan, and Great Basin deserts—represent some of the most physiologically hostile landscapes on Earth. Surface sand temperatures frequently exceed 140°F (60°C), atmospheric humidity hovers near single digits, and standing liquid water is practically non-existent for months at a time. For small ectothermic animals with exceptionally high … Read more
