From creepy crawlies to those that buzz and fly, insects are all around.
These invertebrates with exoskeletons represent the most diverse group of animals on the planet - it's estimated there are up to 10 million different species. From pollinating crops to breaking down waste, insects play important roles in ecosystems and provide valuable services, also to humans.
There's no denying the vital role of bees and other pollinators in global crop production. But pesticides, habitat loss and climate change pose genuine threats to many of the insects we rely on. In France, beekeepers have seen their honey production fall by 50% since the 1990s. To reverse this trend, a group of scientists have taken a different approach to studying ways we can save the species.
Black-legged ticks used to be virtually unknown in Canada, but that's no longer the case. As their population spreads north, so does the threat of Lyme disease. A notoriously difficult disease to diagnose, Lyme disease is carried by an insect that can be as small as a poppy seed.
Insects are among the most successful creatures on the planet. But they're in decline and that would have serious consequences for the world. Entomologist Josef Settele talks to DW about stopping the insect die-off.
