Monarch Butterfly on La Palma

Conservation of Species



Monarch Butterfly

Danaus plexippus


The Monarch Butterfly is threatened with extinction. Already existing for millions of years, the monarch butterfly cannot survive without milkweed (Asclepia) whose leaves are the butterfly's unique source of food, for which La Palma offers excellent climate conditions.

Danaus plexippus


The largest existing butterfly species on the Canary Islands is the magnificent American Monarch (Danaus plexippus).

Monarch Butterfly exist for millions of years. They likely came from the mountains and valleys of Mexico and Central America and in the course of time spread over warmer northern regions.

In search of the milkweed, Asclepia, which are needed to feed caterpillars, they even came to Canada.

The Migration Journey - A Miracle of Nature


By the end of summer the fantastic migration spectacle takes place in North America. 

Millions of Monarch Butterflies swarm in masses and set out to their journey to their winter homes in Mexico.

The Canadian butterfly exlorer Fred Urquhart started his search for those wintering areas in 1938.


Almost 40 years passed tagging butterflies with the help of his wife and throusands of volunteer helpers and watching out for them. Finally, in 1975 the butterflies were found again in the Sierra Nevada in Mexico.

In huge colonies they were attached to a 3000 m high Oyamele Fir Forest. Many butterflies have covered a distance of 3000 up to 4000km.

In February Februar, when temperatures increase, Monarch Butterflies wake up from hibernation.


They mate and swarm in orange- coloured clouds back towards north. This journey is usually based  on generations, as usually butterflies die within 2 up to 6 weeks.

Only the ones that hatched lately in summer undertake the huge migration.  That's how young butterflies mysteriously reach the unknown birthplaces of their ancestors.

Endangered Monarch Butterfly


During the last years the number of monarch butterflies has drastically decreased. In their American habitat the life-essential and wild growing milkweed  is more and more disappearing. Which is also where they lay their eggs and caterpillars only feed from their leaves.

Illegal deforestation of the Oyamel Fir Trees in Mexico, the use of pesticides and intensive monocultures threaten the survival of the precious butterfly.

The "International Union for Conservation of Nature" (UICN) rates the migration of the Monarch Butterfly as in danger of extinction. 

But how can we help? - By providing this unique butterfly its living environment.

Monarch butterfly colonies also exist in Australia and New Zealand. In Europe we find them on the Azores, on Madeira, in West Europe and on the Canary Islands.

And how are things on La Palma?

On the island La Palma you can observe the Monarch Butterfly almost year-round.  

From May to November it can be seen around the entire island, while during the winter months it mainly stays in the southern parts and you can watch them fluttering through Santa Cruz, Puerto Naos or Tazacorte.

Holiday House Casa Monarca in Las Manchas


casa_monarca_tumbonasA  wonderful possibility to live closely with Monarch Butterflies is the Holiday House  Casa Monarca in Las Manchas on the west side of La Palma.

This 100% sustainable designed and energy-self-sufficient Holiday House is a unique opportunity to witness how the butterflies visit the milkweed plants in the garden.


The 1-bedroom Holiday House for 2 persons (+ 1 baby) is nestled on a 3,500 m2 property with a large fruit orchard.


A combination of solar and wind energy fully covers the electricity demand.

The interior of the Casa Monarca features a very homely and cosy living area with a fireplace and a separate kitchen. You also enjoy a gorgeous panoramic view of the Atlantic Ocean.


Meanwhile, there are a large number of butterfly lovers on the island growing Asclepias in their gardens.

This is where the entire Butterfly Cycle takes place


The female, attracted by the smell and colour of the plants, lays a large number of eggs on the bottom side of the leaf.

After 4-7 days tiny caterpillars hatch. As soon as they fed themselves well on the leaves, not only food but also a small dosage of herbicide, that protects them from natural enemies, they crawl on the upper leaf surface.

This whets their appetite for more.

In the following 9-16 days the black-white-yellow ringed caterpillar sheds its skin for four times.

Their forage plant becomes more and more bare and sometimes they even eat the stem. Butterfly lovers should grow sufficient milkweed plants in order to prevent the caterpillars from starving and provide enough plants for the females to lay their eggs.

This may be on the same plant,  below a table or a on a blade of grass.


For this purpose they hang upside-down on a silk-like thread, shaping a "J". In this positon they remain 12 up to 16 hours to shed their skin for the very last time.

It transforms into a pretty green chrysalis with golden shimmering dots.

Little by little their wrap becomes darker and more transparent.

About 8 to 13 days later you already recognize the orange colour of their wings. Depending on the weather conditions 4 to 7 weeks have passed before the butterfly emerges from its chrysalis.


Now the Monarch Butterfly needs some time to stretch out its sensible wings and dry, before taking its first flight. Its wingspan can range up to 12cm and its weight is less than 1 gram.

And it will not be part of the large migration journey to Mexico, however La Palma offers everything it needs  - provided that we all give a helping hand.
