Cotesia (Apanteles) glomerata, a parasitic wasp, has injected her eggs into a caterpillar & now they’re ready to hatch.





“BARRIERS TO MIGRATION” – The theme for World Migratory Bird Day, 9-10 May 2009

Year by year in autumn and spring majestic avian flocks depart for their long journeys following the call of the wild and paths of their ancestors. For some, it is a long, exhaustive and dangerous journey, sometimes stretching thousands of kilometers from the Arctic to the southern tip of Africa and beyond. Migratory birds have to cope with a scarcity of food, stopover sites that are shrinking in area, predators, hostile weather and the expanse of seas, huge mountains and endless deserts. Yet, humans have created additional obstacles to further complicate their journeys.

ESSEX Skipper and small skipper in Ireland

Essex Skipper
The Skippers first discovered in Co Wexford in 2006 and found in larger numbers in 2007, have now been re-determined by dissection to be Essex Skipper. 

Chris Wilson reported in August 2006 the discovery of an unusual butterfly in Co Wexford by Jimmy Goodwin. It was then believed to be the Small Skipper. At least ten adults were seen. The report first appeared in Gaggle, August 2006, which may be found at: >>>

However, some doubts were later expressed about the identity of this butterfy and it was suggested that it could in fact be the very similar Essex Skipper. In 2007, careful examination of internal and external features of a number of specimens has confirmed its identity as being the Essex Skipper Thymelicus lineola and not the Small Skipper Thymelicus sylvestris as previously reported. The main external difference between the two skipper species related to the underside of the tip of the antenna which is a orange or brown in the Small Skipper and black in the Essex Skipper. There are also small differences in markings on the upperside of the forewings of the two species. One of these differences is that the brand of androconial scales is shorter and straighter in the Essex Skipper.

The Essex Skippers preferred food plant for egg-laying is the grass Cock's-foot Dactylis glomerata. Its known habitat includes rough grassland, verges, woodland rides and saltmarsh. Intensive investigation in 2007 revealed additional sites in Co Wexford and substantial numbers of adults. This butterfly was first reported in Britain from Essex in 1889 and currently is spreading northwards and westwards from its headquarters which some years ago approximated to the area south of a line from the Humber to the Severn. It has recently become established in the southwest of Wales. It occurs throughout Europe and in Northern Africa eastward to eastern Asia. It is not known as a migrant and how and when it arrived in Co Wexford is a mystery.


Small Skipper in Ireland


A photograph of a skipper taken in the Timahoe-Drehid area, on 24 July 2011, appeared to be that of the Small Skipper and fieldwork carried out in 2012 confirmed the presence of a population of the species in Co Kildare.
The Small Skipper was found at low density over a distance of more than two kilometres along the corridor of the abandoned Bórd na Móna Industrial railway which intersects the road from Drehid Cross to Timahoe Cross.

It is widely distributed in England and Wales and in the past decades has spread northwards and into Scotland. It is found throughout mainland Europe, North Africa and eastwards to Iran.


Typical habitat of the Small Skipper includes rough tall grassland, verges, open fields and woodland rides. In Britain it shares the same habitats as the Essex Skipper (Thymelicus lineola) and as the two species are so very similar in appearance they are often not distinguished in the field.

Larval Food Plant:

Its preferred larval food plant is Yorkshire Fog (Holcus lanatus) and others include Timothy and False Brome and since these grasses are common in Ireland it is considered that this species, if left to its own devices, will eventually become widespread.

A "blind" Peacock

Most butterfly species have aberrations - untypical forms, which occur for genetic reasons. Richard McCafferty reported (2006) a "blind" Peacock from Glenties, Co Donegal which corresponds to the known aberration belisaria Oberthür. This form of the Peacock is a melanic form where the ocelli (eye spots) are replaced by pale cloud-like markings and the black spots on the costa (anterior margin of the wing) are joined. This aberration is variable and may effect the forewing or hindwing only. The Peacock reported by Richard has the variation in the hindwing and he reckons that its wing span was in the range 45-50 mm rather than a more typical size well in excess of 60 mm.

Previous reports from Ireland appear to be very sparse. Dudley Westropp reported one from Co Offaly in 1900 and Robert Allen of Co Armagh Wildlife Society saw one c.1984 near O'Rourke's Park where the road running past Silent Valley turns down to Annalong, Co Down.
Those who have access to The Butterflies of Great Britain and Ireland (Eds Emmet and Heath) will see an illustration of this variation (Plate 11) and a photgraph of a specimen from the Cockayne Collection on the Natural History Museum, London website can be found on the NHM website: >>>

Monarch Migration

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.

Monarch butterflies (Danaus plexippus) from the eastern North American population make remarkably long migratory journeys in the autumn, some extending more than 3,500 km from Eastern USA and Canada to over-wintering grounds in the neovolcanic belt in Central Mexico.

Hibernating Butterflies

In autumn the Small Tortoiseshell frequently enters houses in order to seek a sheltered spot to hibernate. 

In earlier times in Ireland when many rooms were unheated the butterflies were able to hibernate safely  until the sun of late March and early April awoke them and they were ready to fly off. 

Modern houses are usually centrally heated and the SmTs awake in the winter and start to fly around. 
They use up their energy reserves and are unable to find adequate natural sources of nectar and thus are likely  to die before the onset of spring. 

I suggest the best approach is to try to feed them a mixture of honey and tepid water or fructose and water.
Small amounts of these mixtures can be absorbed on some cotton wool and placed on a sunny window ledge or at a suitable distance from an electric lamp. 
The reason for the cotton wool is to avoid the butterfly getting stuck in the solution and thus damage its wings.

When the suitably warmed butterfly is placed near the treated cotton wool it should then extend its narrow proboscis  (tubular tongue) and begin to feed. It will probably do so for ten or fifteen minutes. 
Afterwards it should be left in a roomy box in a cool place and allowed to settle down. If needs be it could even be left  in the fridge in a shoebox for twenty minutes. 

The box should then be left in a dark shed or other cool dark place and checked about mid-March. 
Make sure the box is mouse proof! The butterfly should be released on a fine warm day in early April.

Researchers at the Ulster Museum and Butterfly Conservation have made a startling new discovery: a new species of butterfly in Britain and Ireland (2001); the first to be discovered for over 110 years. The new species of Wood White (scientific name: Leptidea reali) looks very similar to the ‘normal’ Wood White (Leptidea sinapis) and has only been identified by examining the genitalia of museum specimens.   

So far, the new species has been found only in Ireland (both Northern Ireland and the Republic of Ireland) and the specimens examined from Britain have turned out to be the normal species of Wood White.  

The discovery was jointly made by Brian Nelson and Robert Nash (Ulster Museum) and Maurice Hughes and Dr. Martin Warren (Butterfly Conservation). This has helped explain a curious phenomenon revealed recently in The Millennium Atlas of Butterflies in Britain and Ireland. In Britain, the Wood White is true to its name and found in woodland rides but is declining rapidly, whereas in Ireland it occurs in more open habitats (such as road verges, scrub and sheltered grassland) and has expanded rapidly northwards in recent decades. The phenomenon can now be explained because they are two different, but almost indistinguishable, species that may have different ecological requirements.  

Maurice Hughes (Regional Development Office of Butterfly Conservation in N. Ireland) was one of the research team making the discovery. He said “This is an exciting and important discovery, which helps explain the puzzle of why the Wood White has fared so differently in Ireland compared to Britain. In Ireland we have found that the ‘normal’ Wood White is apparently confined to the scrubby woodland around the Burren in County Clare (making it the rarest Irish butterfly). The 'new' species occurs throughout Ireland, but is absent from Britain (the only one). It has also highlighted the need for renewed effort to conserve all populations of this highly threatened species. We will now be conducting further work in both Britain and Ireland to examine ecological differences and see whether we can find characteristics that can be used to separate the two species in the field.”  

The new species does not yet have an English name, although the scientific name reali is derived from the person who first discovered it in continental Europe. So perhaps “Réal’s Wood White” would be appropriate.

Status and aims

Butterfly Conservation Europe was formed in 2004 as an umbrella body with the aim of stemming and reversing the rapid decline of butterflies, moths and their habitats across Europe. It also aims to promote all activities and initiatives to conserve butterflies, moths and their habitats, including increasing the resilience of ecosystems across Europe through adaptation of land uses to sustain biodiversity in the face of climate change.

A clear focus of the organisation will be to work with a wide range of partners in Europe, both governmental and non-governmental, to implement the Conservation on Biological Diversity with respect to butterflies and moths and their habitats, and to contribute to achieving the EU target of halting biodiversity loss by 2010.

The geographical scope of BC Europe comprises all countries that are members of the Council of Europe and includes the Azores, Madeira, the Canary Islands, Russia to the Ural Mountains and the whole of Turkey. 

BC Europe is a non-profit making organisation registered in the Netherlands and comprises a non-incorporated consortium (Network) of institutions and organisations working to achieve the mission of Butterfly Conservation Europe.
