28 THE RURAL VOICE
the future for that species is in doubt.
Consequently, the use of herbicides,
pesticides and chemical fertilizers has
been suspected as one of the culprits
in reducing butterfly numbers.
While the survival of butterflies
depends in part on land -use methods,
we must also acknowledge that
weather conditions and predators take
their toll Birds, frogs, dragon flies
and spiders enjoy butterflies as meals.
Urban development, a well-known
usurper of agricultural land, is
another enemy of butterflies. Homes
and their aftergrowths such as
highways, defoliated roadsides and
manicured lawns, rob butterflies and
their offspring of a major food
source.
t would be convenient to be able
to say to farmers and gardeners
that butterflies are important
pollinators. But according to
Tom Mason, curator of
Invertebrates at the Metro Toronto
Zoo, this is not the case. Although
butterflies are pollinators, bees, ants
and wasps play far more important
roles.
But do we really need to find a
practical role for butterflies?
Consider these facts. In the rough,
butterflies attract enthusiastic
watchers, although I'm told this
hobby can become addictive.
Watching can also be accomplished
in the many butterfly museums which
have sprung up around North
America. England boasts 74
greenhouses devoted exclusively to
butterflies. The popularity of
butterfly conservatories has spawned
a new industry, butterfly farming, an
industry which is government
regulated both here and abroad. In
New Guinea, for example, farmers
are taught which larval host plants to
watch and tend. The resulting
butterflies are caught and shipped by
permit to museums and collectors
around the world. The resulting
financial returns are used as
incentives to ensure that the forests,
where most of the species live, are
protected rather than destroyed.
While the popularity of watching
is increasing, butterfly collecting is
on the decline. Photography and
gardening represent current
approaches to conserving this
beautiful natural resource.
