October 2011 – “In Search of the Two-tailed Pasha”

This article on my Portuguese trip last October has now been published in Butterfly Conservation Ireland’s 2011 Annual Report. One of the highlights of this trip for me was the surprise discovery of a wonderful Borboletario or butterfly house in Lisbon’s Botanic Gardens where I was surrounded by beautiful Monarch butterflies. The migration cycle of this butterfly in North America is one of the most fascinating phenomena in Nature. They overwinter in Mexico and then move northwards in Springtime in a wave that goes all the way up to Canada – a journey of almost 3000 miles! I was talking to someone last Wednesday night who lives in Toronto and he was telling me how they await with joyful anticipation the arrival of the Monarch in their garden every year. It has greatly extended its range since the middle of the 19th century, colonizing New Zealand in 1840, Australia in 1870 and Canary Islands in 1880. It was first noted as a resident in Southern Iberia in 1980 and this photograph is courtesy of Simon Wates.
