According to experts, a rare butterfly that was once abundant in the peatlands of Greater Manchester is now "flourishing" after being reintroduced in 2020.
The large heath butterfly used to be so common in the area that it was given the nickname Manchester argus.
The Liverpool and Manchester Railway arrived in the 19th century, though, and completely destroyed the environment.
The species is currently "breeding strongly," according to wildlife experts, who expressed their "optimism" about it.
A spokeswoman for The Wildlife Trust for Lancashire, Manchester, and North Merseyside said they reintroduced the fluttering insect in north-west England in 2020 and 2022, and another batch is scheduled to be released this summer.
It came after the regrowth of vegetation and drained peat.
According to Jo Kennedy, coordinator at the Great Manchester Wetlands Partnership, "more than 98 percent of the lowland peatlands in our region have been lost, leaving a significant gap in our biodiversity. ".
experts were "excited to be able to bring the Manchester argus back to Manchester," she said, citing Chester Zoo, Manchester Metropolitan University, and Natural England.
"It has taken a real team effort, but with three butterfly releases now accomplished, the population is breeding strongly and we are really optimistic about its future. ".
Following the legal collection of six pregnant female butterflies from a population at Winmarleigh Moss near Garstang, Lancashire, the butterflies were reintroduced.
Before the caterpillars were released, Chester Zoo staff took care of the butterflies while they laid eggs.
To aid in the protection of the butterflies, the precise locations of the reintroductions have not been disclosed.
The reintroduction was "part of our mission in preventing extinction worldwide," according to Helen Bradshaw of Chester Zoo.
We are overjoyed to witness the remarkable resurgence of these rare butterflies in their natural habitat following years of effort and commitment.
Reintroductions can be incredibly effective when done correctly, as in this case. ".
it's the argus butterfly.
- The argus butterfly (aricia agestis), which once flourished in the UK, has been declining as a result of changes in agricultural practices.
- The species lives in swampy peatlands and is sedentary, rarely moving more than 100 meters in a single day.
- Their caterpillars have the ability to endure extended periods of hibernation.
- The cocoons are green with black stripes, giving them the ability to blend in and fend off predators. They hang from plants.
- In Scotland and northern England, there have been surviving populations.
South West Scotland Butterfly Conservation, UK Butterflies, and the Forestry Commission are some of the sources.
