Boost for butterflies as gardeners take a walk on the wild side

The Daily Telegraph reports dwindling sightings of the insects mean people are being encouraged ‘rewild’ their garden by leaving parts of it for nature. A poll of over 2,000 people by BBC Gardeners’ World Magazine found that 54 per cent of people had created an “uncultivated area” in their garden last year, up 11 per cent on the year before.

Kate Bradbury, wildlife editor at the magazine, said gardeners keen to help boost butterflies could also resist the urge to clear up dead leaves or cut back dead stems from which chrysalides might be hanging.

Climate change: Dragonflies spread north in warming world

The BBC reports dragonflies are moving northwards across Britain and Ireland as temperatures rise. More than 40% of species have increased their distribution since 1970, while only about 10% have declined, according to a new report.

Experts from the British Dragonfly Society say it’s an indicator of the effects of climate change. There is concern over the loss of populations of insects due to factors such as pollution and habitat loss. 

Light pollution from street lamps linked to insect loss

The BBC reports scientists say light pollution may be contributing to “worrying” declines in insects seen in recent decades. In a UK study, artificial street lights were found to disrupt the behaviour of nocturnal moths, reducing caterpillars numbers by half.

Modern LED streetlights appeared to have the biggest impact. There is growing evidence that insect populations are shrinking due to the likes of climate change, habitat loss and pesticides. Factors are complex and varied, including the steady loss of forests, heathlands, meadows and marshes, overuse of pesticides, climate change and pollution of rivers and lakes. 

Flying ants could swarm Euro 2020 final at Wembley

The Observer reports swarms of flying ants could swarm to Wembley and cloud the Euro 2020 final, after a radar detected millions of bugs over London and the south-east on Friday. As luck has it, the final between England and Italy is taking place on Sunday, which could fall into the mating period of ants, which go on a “nuptial flight” in huge numbers between June and September.

Although the Met Office has forecast “promising” weather for Sunday, it also picked up on the phenomenon potentially coinciding with the fixture and becoming a nuisance for buzzing players and fans.

Nature belts aim to bring lost life back to edge of towns

The Times reports bees, butterflies and birds could return to the outskirts of towns and cities under plans being considered by ministers to create a “wild belt” to restore depleted natural habitats. Robert Jenrick, housing secretary, is understood to be keen on the idea of wildlife corridors as a way to encourage greater biodiversity across the country.

Count bug splats on cars to study insect decline, UK drivers urged

The Guardian, and iNNewsreport a new app that tracks bug splats on car number plates will enable UK citizen scientists to help shed light on the worrying decline of insects.

Older drivers will remember scrubbing large numbers of splatted insects from windscreens after journeys in past decades. But a 2019 study that analysed car registration plates after trips in Kent found a 50% fall in splatted bugs compared with 2004.

The charity Buglife has now launched the free Bugs Matter app to enable people to collect valuable data. Users start by cleaning their number plate before a journey, which is then tracked by the app to collect location and time data.
