This fun educational video from Harvard Medical School's Centre for Health and Global Environment & Free Range Graphics launched a discussion about biodiversity.

It teaches about the importance of biodiversity and that humans are part of the web of life.

Monarchs in the news 2014

Fall migration south begins approximately mid-August for northern Monarchs. After crossing half the continent of North America, the monarchs reach their overwintering sanctuaries, located at approximately 19.60N, 99.60W, in Central Mexico around November each year.

It's an area only 70 miles wide and within it only 12 mountaintops have the habitat the butterflies need to survive. The Monarchs roost for the winter in oyamel fir [Sacred Fir (Abies religiosa)] forests which are at an elevation of 2400 to 3600 meters and where temperatures range from 0o to 15o C. The humidity in the forest prevents the monarchs from drying out allowing them to conserve their energy. This provides an ideal microclimate for the butterflies. 

Spring migration north begins in March (untill approx. mid-June), from the monarch sanctuaries of Central Mexico. After living off their fat reserves all winter, tens of millions of Monarchs will head northward producing the next generations of Monarch butterflys.

Hot and Cold

Snow around 10th May and temperatures ~29C on 20th! 

Cold temperatures moved across North America last week (9th May) and kept the Monarchs from advancing northward. It even snowed in some parts of Canada, where monarchs had arrived the week before. 
At the same time a massive migration of Red Admiral butterflies was underway.

LADYBIRDS

Please send your records to DNFC: ladybird@dnfc.net   

 

The Harlequin Ladybird

News Update from The Harlequin Ladybird Survey website (UK), 31/10/2007 

Why are there very large numbers of ladybirds this autumn? 

They are likely to be harlequin ladybirds, an alien species that is spreading fast in the UK. Harlequins are active later in the year than most other ladybird species. In autumn they gather in large groups at overwintering sites, which are often in or on buildings. They leave chemical traces that attract others of the same species to that spot. They do not normally breed indoors and should leave buildings in the spring.

Because of its threat to wildlife Damian McFerran of CEDaR and Roy Anderson of DARDNI in Belfast are keen to see what members of the DNFC can find out about Harlequin ladybirds (Harmonia axyridis) in Ireland.

It's worth viewing the UK annual spread maps at =>>

the most invasive ladybird on Earth.

A new ladybird arrived in Britain in the summer of 2004 called the Harlequin ladybird (Harmonia axyridis)

It is also known as the Multicoloured Asian Ladybird and the Halloween Ladybird. 

It has already invaded much of northwestern Europe

It was introduced to North America in 1988, and is now the most widespread ladybird species on that continent.

The harlequin ladybird (Harmonia axyridis) has a very variable appearance!

Colour plate from The Harlequin Ladybird survey web site: http://www.harlequin-survey.org/

The most common forms in the UK are  
orange with 15-21 black spots and black with two or four orange or red spots

The Harlequin ladybirds are most commonly found on deciduous trees, such as lime, sycamore and maple, and on low growing plants such as nettles. They will also inhabit reedbeds, coniferous woodland and crop systems.

Harlequin ladybirds feed most commonly on aphids, but also feed on scale insects, adelgids, eggs and larvae of butterflies and moths, many other small insects, including other ladybirds, pollen, nectar, and sugary fluids, including honeydew and the juice from ripe fruits.
