Almost one-third of Europe's butterflies are in decline and nearly one in 10 species is threatened with extinction in the region, conservationists warned today.
The large blue butterfly – which was successfully reintroduced to the UK after dying out here – is endangered throughout Europe, according to the European red list assessment of species at risk.
And the Duke of Burgundy and Lulworth skipper, which both suffered their worst year in the UK last year, are in decline in many countries across the continent.
The release of the red list, commissioned by the European commission, also revealed that 14% of dragonflies and 11% of a group of beetles which rely on decaying wood were at risk of extinction.
Some 22 species of butterfly, 29 types of the "saproxylic" beetles and five different dragonflies are also at risk of becoming extinct globally, according to the assessment led by the International Union for Conservation of Nature (IUCN).
Conservationists said a loss of habitats, including traditionally farmed grasslands, woodlands and wetlands, was the major factor affecting insect species.
Dr Martin Warren, author of the report on Europe's butterflies and chief executive of Butterfly Conservation in the UK, said insects were being hit by loss of grassland habitats due to both intensification of agriculture and abandonment of farming land.
Nearly one-third (31%) of Europe's 435 butterfly species have declining populations, the report found.
While the large blue butterfly's reintroduction in England has proved a success, it is "very much the exception" as it is declining in every country where it occurs, Warren said.
But, he added, conservation efforts to re-establish populations in the UK after the butterfly vanished in 1979 showed what can be achieved if the right steps are taken.
Most butterflies at risk are in southern Europe, said Annabelle Cuttelod, IUCN coordinator of the red list.
Along with changes to agriculture, species are threatened by climate change, forest fires and the expansion of tourism, she said.
The Madeiran large white butterfly is critically endangered (possibly extinct), having not been seen on Madeira for 20 years, and the Macedonian grayling butterfly is critically endangered because quarrying activities are reducing its habitat.
Warren said most of the butterflies listed occurred on grassland or habitats which had been managed by humans and had benefited from traditional agricultural processes.
But now, he said, "traditional systems are disappearing in a big way".
"In the 1950s and 60s we had massive losses of habitat in the UK, and it is still going on to a lesser extent, but in Europe big changes have been going on in the last five to 10 years."
He added: "We lost a lot of our flower-rich meadows in the 50s and 60s, while they are losing theirs at a rate of knots now."
Intensification of agriculture is destroying habitat in some areas, while grasslands in many mountain regions in the Alps and Pyrenees are being abandoned and falling into a poor condition because livestock farming is not financially viable.
Warren called for more support for traditional farming systems to help insects such as butterflies, which he said were very good indicators of changes to the environment.
Jane Smart, director of the IUCN biodiversity action group, said: "When talking about threatened species, people tend to think of larger, more charismatic creatures such as pandas or tigers, but we mustn't forget that the small species on our planet are just as important and are also in need of conservation action.
"Butterflies for instance, play a hugely pivotal role as pollinators in the ecosystems in which they live."

UK's first major wave and tidal power schemes in Scotland to be unveiled
E.ON among energy companies competing with local firms for scheme predicted to create 'Saudi Arabia of marine energy'

The first fully fledged schemes to harness the UK's immense potential for wave and tidal power will be unveiled by the Crown Estates and Scottish government this morning.
About 20 firms have been in the running to install what are touted by the Crown Estates to be the world's first commercial wave and tidal schemes, in the Pentland Firth off northern Scotland and around the Orkney islands.
Alex Salmond, the first minister of Scotland, has predicted the area – where the Atlantic meets the North Sea – will become the "Saudi Arabia" of marine energy because of the region's powerful currents and tidal surges.
It is thought the first devices will be operational by 2020, producing power for as many as 700,000 homes, but will require a multibillion pound investment programme.
There is already speculation that major power companies such as E.ON, Scottish and Southern Energy, which already operates the UK's largest hydro schemes, and Scottish Power, a heavy investor in wind farms, will be among the winning firms and joint ventures.
The small Edinburgh-based wave power company Pelamis Wave Power, which has pioneered marine energy with its "snake" device being tested off the coast of Portugal, is also said to have been chosen.
Niall Stuart, chief executive of Scottish Renewables, told The Scotsman that today's announcement was the "dawn of a new era in a new industry that will be grown and based in Scotland, but that has potential new markets all over the world."
Today's announcement follows last month's confirmation that £75bn will be spent on developing at least 25GW in offshore wind power at nine sites around the British Isles, including two off Scotland.
Last year, Scottish Renewables estimated that offshore wind, combined with predicted wave and tidal schemes in Scottish waters, could deliver a 30% cut in Scotland's total CO2 emissions. That would be the equivalent of taking 4.5m cars off the road and would account for 89% of Scotland's total electricity demand.
However, power companies and renewables campaigners believe far greater investment is needed to properly exploit this renewable energy resource. They believe the UK has failed to properly invest in the electricity grid network to connect Scottish green power projects to southern markets, and attack the National Grid for using a geographical system which charges power firms in Scotland more than schemes nearer London to transmit electricity.
