Staple diets in Nigeria can be improved by the addition of insect powders, rather than serving recognisable forms of insects.
These insects are basically little machines that convert carbon-rich leaves into nitrogen-rich poo.
As environmental engineers, invasive caterpillars can have remarkable effects on water quality and soil conditions. But from a climate perspective they’re pretty much a nuisance.
Many living organisms generate and even detect static electricity in their natural environments. We must understand more to ensure we don’t disturb these delicate processes.

A fly does some of its digesting outside its body before it even eats any food.
Male mosquitoes gather around humans, likely in an attempt to mate with blood-sucking females.
Can spider webs predict the onset of winter? Probably not.
Insects are changing their behaviour as they prepare for winter.
Metamorphosis of Lyriste plebejus: the cicada, finally out of the ground, transforms from the larval stage to its adult appearance.
The Massif des Maures was devastated by fires this year, but the region’s hardy cicadas continued to sing thanks to their unique survival methods.
Environmental DNA is a promising tool for tracking species in freshwater ecosystems like Oregon’s Elkhorn Creek.

Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.
Beetles exposed to elevated carbon dioxide emerged later and smaller and had a reduced chance of making it to adulthood.
This is the first time researchers have calculated the amount of carbon released from the world’s decaying wood. They found insects play an enormous role.

Many small animals make their teeth and claws from a smooth blend of proteins and heavy elements. These materials can form very sharp tools that make it possible to cut tough substances using tiny muscles.

Biological control strategies curb pests using other species that attack the invader. A biologist explains why it can take more than a decade to develop an effective biological control program.

The increasing prevalence of white LED streetlamps spells worrying population declines for insects like moths.
Sirex noctilio is an invasive woodwasp that causes huge damage. Understanding what attracts it can help repel it.
Inserting electrodes into insects helps scientists understand what attracts these insects – and, stemming from that, how to trap them and protect crops.

Usain Bolt can run at about 6 body lengths a second. An arachnid in California can do 322.
Efforts to manage the invasive caterpillar
L. dispar have cost billions of dollars in Canada and the United States.
The caterpillar, Lymantria dispar, has eaten through 17,000 square kilometres of trees since the 1980s. The invasive insect was imported in the 1880s to launch a North American silk industry.
Campers at the “Mosquitoes & Me” summer camp in Des Moines, Iowa, learn about mosquito science through hands-on outdoor activities.

A hands-on approach to learning about bugs can help students from urban communities take an interest in science.
Over 40% of all insects, like this tropical dragonfly, are in decline.
New data from tropical and subtropical regions suggests insects are declining thanks to dammed rivers
Coprophanaeus lancifer, a large seed-disperser dung beetle in the Amazon.
We know surprisingly little about the millions of animals, plants and birds that live in the Amazon – here’s how we can understand them better.
Researchers crack the conundrum about why African Baobab trees in southern Africa differ in terms of fruit production.
Baobab flowers have male and female parts but individual trees appear to be favouring one rather than the other. To keep tree populations healthy and fruitful, both types are needed.
