England: Adonis blue butterfly comeback


Adonis blue

From the BBC:

One of Britain’s rarest butterflies has returned to a spot where it has not been seen for more than 40 years.

The Adonis Blue, classified as a priority species, is usually only found at a few places in southern England.

But it has returned in numbers to a former site in the Cotswolds, Gloucestershire, after a National Trust campaign to restore its habitat.

The insect’s numbers were decimated 50 years ago when a lot of its natural habitat, chalk grassland, was lost.

Åland islands: Glanville fritillary butterfly.

Good year for rare Marsh fritillary butterfly in Devon: here.

October 2010: Record numbers of marsh fritillary butterfly webs have been counted this month at Devon Wildlife Trust‘s Volehouse Moor nature reserve in north Devon. This success follows intensive work at the north Devon site: here.

Almost 4,000 marsh fritillary caterpillars were distributed on suitable habitat by Wild Ennerdale Volunteers, Forestry Commission staff and Butterfly Conservation under a licence from Natural England: here.

    Resurgent monarchs fluttering to Mexico

    Following recent declines, butterfly numbers increasing

    Tuesday, November 8, 2005

    MEXICO CITY, Mexico (AP) — As many as 200 million monarch butterflies may migrate to Mexico this year — a nearly tenfold increase over 2004, when unfavorable weather, pollution and deforestation caused a drastic decline in the population, environmental officials said Tuesday.

    Last year, fewer than 23 million butterflies survived long enough to leave habitats in the United States and Canada for sanctuaries in the state of Mexico, which borders Mexico City, and neighboring Michoacan state.

    That was at least 75 percent lower than expected, but should usher in a monarch resurgence this year, officials said.

    “In the past, very low numbers have recuperated and produced surprisingly high populations,” said Jose Bernal, director of inspection for Mexico’s environmental protection agency, Profepa, following a news conference to kick off Mexico’s monarch butterfly season.

    Public helps map butterfly’s trips

    By Christopher Hall
    Special to Louisville Courier-Journal

    Monarch butterflies undertake one of the longest insect migrations in the world — from Canada to Mexico and back again.

    Only recently have researchers begun to understand the migratory patterns, much less how generation after generation of butterflies know to return to the same area, sometimes even to the same trees, on their migrations.
    Now scientists are getting help from the public.
    Sunday, the mother-son team of Anne and Robert Richardson of Avon, Ind., held a four-hour training session at the Falls of the Ohio State Park Interpretive Center for about 15 people interested in participating in a citizen-science project monitoring monarchs.
    The Richardsons have been helping with the University of Minnesota’s 10-year-old Monarch Larva Monitoring Project for about five years, doing research and training others to help.
    “We can be part of the research. We can be a part of helping scientists answer these questions,” Ann Richardson said.
    “A lot of what we already know is a result” of the project, she said.
    Robert, 16, has already presented some of his own research findings on monarch feeding patterns and the butterflies’ preference for certain species of milkweed to experts at a conference in California in 2005.
    “It’s definitely been an educational experience,” he said. “I learn new things every day.
    “It’s very interesting to see the development of the information being built up on the species.”
    One of the primary focuses of Sunday’s training was finding local patches of milkweed, the monarch’s sole food source.
    The unpopular weed is becoming scarcer, one of several factors that may be jeopardizing the annual monarch migrations, Ann Richardson said.
    The training class was scheduled to take a brief trip to a nearby plot of milkweed, which in itself was a difficult task, according to Connie Farmer, interpretive naturalist at the park.
    “I mean, we had a difficult time finding milkweed, and it just goes to show it’s just not around like it used to be,” she said.
    One approach advocated for helping to preserve the migrations is for families to set aside “butterfly gardens,” or small patches of milkweed, for the butterflies.
    David Coyte of the Knob and Valley Audubon Society participated in Sunday’s training and said members of the local chapter are glad to be involved in the monitoring.
    “It’s a fascinating issue,” he said of the butterfly migrations.
    “Any time that we can better understand the interconnectedness of bio-systems and living organisms with each other, then we improve our own chances of survival,” Coyte said.
