The word Pest is itself noisome. That's my objection to "Integrated pest
management". Bad word.
I suppose that, from the point of view of the milkweed, the monarch is a
pest, always supposing that the milkweed is unaware of the merits of
pruning. Certainly the milkweed responds to the action of the monarch by
increasing toxicity in its leaves, which would suggest that it dislikes
the chomping, or would like to limit it. ;-)
As the milkweed itself (some species) is a pest, perhaps the monarch
could be regarded as a biocontrol organism. Again, a permit would be
Monarchs, and other butterflies, are a crop now, though, reared by
countless butterfly farmers, and therefore under the aegis and auspices
of the USDA whether they are listed as pests or not. So, argue though
you may, you will not win. Domestic animals, maybe?
I noticed, a while ago, that one of your California butterfly farms was
selling cabbage whites for release at weddings. Now, you know that ain't
What we fall back on, with these regulations, is the bottom-line
question: What if everybody wanted to do it.
If everybody wanted to rear silkmoths? mantids? Red Admirals? For their
own enjoyment ... well, the first, knee-jerk reaction, I have to admit,
is, "Wouldn't it be loverly."
Alas, there are deeper matters at stake here.
But, like Chris, I deplore the use of the word and concept "pest". I
suppose we're stuck with it, though.
