The Rural Voice, 1994-02, Page 30Thinking of butterflies and summer In the sunny south the butterflies are resting up for their trip north. But will they find a welcoming environment when they return? By Carl L. Bedal There's no better time than February to remember summer and its buuerflies, those flying flowers which flit about our gardens in what seems utter freedom. The Monarch, our best known butterfly, is still wintering in Mexico before starting its flight north for the summer. Here in Ontario, a few select butterflies are housed in warm comfort at the Metro Toronto Zoo and the Canadian Museum of Nature in Ottawa. In Florida, thousands of colorful butterflies are encamped outdoors in Butterfly World, near Ft. Lauderdale. I vividly remember my visit there last month, a visit which left me with the impression that there's nothing better for the soul than a winter rendezvous with butterflies. "It's time to wake up," said the park guide as she gently shook the fragrant plants which had been overnight hosts to sleeping butterfl ies. It was only 9 a.m., an early hour for butterflies, especially on a winter day in Florida, but the gates to Butterfly World, an outdoor museum 26 THE RURAL VOICE Photo: Female Monarch Butterfly in Mexico by Barry Peers, Canadian Museum of Nature. devoted exclusively to butterflies, had opened to visitors. The guide simply wanted more action from her charges because the many varieties of butterflies in the park's three aviaries were not yet active. Roused by the guide's wake-up call — or was it the music of Mozart gently playing in the background? — butterflies of every hue took off and fluttered around inside screened -in buildings landscaped with waterfalls and semi -tropical plants, the latter carefully selected to attract butterflies. It was easy to imagine heaven under these conditions of seeming contentment, surrounded by colour, exposed to fragrance, warmed by sunlight, and for the butterflies, only a short flight to sweet nectar. Chuang Tzu, a 4th Century B.C. Chinese philosopher, summed up the feeling when he wrote, "I do not know whether I was then a man dreaming I was a butterfly or whether I am now a butterfly dreaming I am a man." Unfortunately, butterfly heaven may be coming to an end. Butterfly populations, like human populations, are sensitive to their environment. Consequently, changes in the environment, even small ones, can affect butterfly survival. The corollary, of course, is that the size of the butterfly population reveals the condition of our surroundings. Already, some species like the Xerces (a blue butterfly after which the Xerces Society, a group of butterfly devotees, was named) are extinct and two species in Ontario, the Karner Blue and the Frosted Elfin, are endangered. arry Peers, biologist at the Canadian Museum of Nature in Ottawa, expresses concern about the Monarch population in Ontario. The reports he has received indicate that the monarch population has decreased significantly in the last two years. While he thinks the cool, wet summer of 1992 and the flooding in the mid -West in 1993 may have played a role in reducing this population, Peers considers our modifications of the environment a more likely contributor to this sudden decline in its numbers. While the decrease in numbers 1 J ��v
