From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.IN THE mild winter and hot summer the common wasp, Vespula vulgaris, has flourished. Its numbers are well above the norm, and you could be forgiven for thinking that a plague of biblical proportions is imminent, writes Martin Walker.
Wasps, says Carl Clee, honorary curator of aculeate hymenoptera (stinging insects) at the Liverpool Museum, "are extremely efficient predators". Vespula vulgaris is omnivorous, eating grubs, caterpillars and insects as well as leaves, fruit, nectar and sugar. It lives in well-ordered communities in which each individual plays a clearly defined role.
As with other insects of the order hymenoptera (insects with four transparent wings) this society is presided over by a queen, who rules supreme, even dictating the sex of the wasps produced in her nest. She does this by keeping sperm separate from the unfertilised eggs.
Some eggs develop into male wasps (drones), whose only purpose is to mate; others into female workers who leave the nest to forage for food and defend the nest against attack. At the end of each summer, new queens are produced by selective feeding - only these survive the winter.
The sting is carried by female workers alone. "Wasps do not sting indiscriminately, but respond only to what they see as being threatening," said Mr Clee.
