Invertebrates underpin Earth’s ecosystems – so if their numbers decline, the ecological damage will be felt far and wide.
To limit our impact on the planet, one solution could be to replace meat with insects. Children could set an example.
Humans are ‘noisy neighbours’ whose behaviour has long lasting ecological and evolutionary effects on other species.
Few animals have babies without sex, so biologists assumed asexual reproduction must have evolutionary drawbacks. But a self-cloning Australian grasshopper shows things might be more complicated.
Staple diets in Nigeria can be improved by the addition of insect powders, rather than serving recognisable forms of insects.
When natural habitats are isolated it means species are less able to migrate, leading to less genetic variation and species diversity.
Insect populations are falling as what they eat becomes more like iceberg lettuce and less like kale.
They’re just one of many insects facing dramatic population decline.
Small animals are the fabric of the world around us. Without them everything would crumble.
Insects have often been described with words like “disgusting” and the idea of eating them horrifies some people. But this needs to change as they can be an important food source.
