Description
Wingspan: 95 - 100mm
Worldwide Range: Azores : coastal districts of Canary Is-excluding Lanzarote.,N Africa,S Portugal,S Spain- province Malaga,Mauritius, India, Papua New Guinea & other E Indian Is.,Australia,New Zealand,S Peru to Canada : N,C & S America
Distribution: Occasional vagrant/migrant to Azores : Lanzaote : S & W Portugal : Gibraltar : more rarely Ireland : SW England : S France

UK Conservation Status -
Habitat: As a migrating species any habitat containing host plant
Similar Species -
Overwinters as: Adult
Observations: The Monarch is a large butterfly with a larger reputation for its ability to migrate long distances in a short time as well as being one of our rarest migrators.In autumn, as the weather cools, large numbers fly south from their breeding grounds in Canada,via the Gulf Coast, then to Oyamel Fir Forests of Mexico where the overwinter for three months,a distance of 2500 miles.The following February and March the process reverses as they migrate north,the females laying eggs as they go with these offspring also heading north to the Canadian breeding areas.Most of the original butterflies perish on the way, but not all.
It was first thought these butterflies used the sun to guide them to their targets but experiments have proven beyond doubt that the guidance mechanish is not in their head, but in their antennae.
The first Monarch in the British isles was in 1876 when a single specimen was recorded from Neath in south Wales. As can be seen above the first records were considered vagrants or by accidental importation on plants, something that changed when 40 were recorded in a single year proving immigration was the most likely cause.
The total numbers now recorded is approximately 900 with most appearing along the SW coast of England,Scilly Isles and southern Ireland.
In 1981 there were 131 sightings along with many North American birds which would seem to indicate migration due to heavy storms and strong winds,although with the butterfly now established in places like Spain and Portugal,the Canary Isles and Madeira the origin of the migration could be placed in doubt.
As can be seen below the Monarch larvae feed on many different species of Asclepias which produce poisons which are passed onto the adult as a defence mechanism against birds and other predators.The orange wings with black veins and white spots are used as a warning signal to the predators, a pattern used by other mimic,non poisonous butterflies of which the Viceroy Limenitis archippus is one of the well known species.
Some birds have learnt how to strip out the body contents discarding the toxic elements and can take large numbers of Monarch butterflies.
Although male and females share the same warning colouration the male can be separated by the sex brands on vein 2(V2) of the hindwing and the female usually has darker veins.
