Not too sure on this, but I believe the reading I've done on this subject states that the Monarch Butterfly caterpillar is affected by the Bt corn pollen which is wind-carried to its sole food source - milkweed leaves. Pollen is the lovely yellow dusting that covers your car in spring and summer. BTW, I'm with ya all the way on the lima bean thang! Nasty lil buggers, ain't they?! :) Valerie > >But, even with all the corn we grow here I have never ever seen > >a Monarch eating corn.

OPPS, I don't want to start a controversy about Lima beans. -- Valerie :) aka: Breeze ICQ# 3953329 http://www.crosswinds.net/~breeze62/
