Jane,
If you try iris for bait go with buds or flowers.

As to the latest suggestions,
row cover: The caterpillars live underground and emerge at night to
feed; also, this collection isn't broccoli. I suppose row cover (Reemay)
could be laid on the beds in summer, if I knew exactly when to do so,
but there is always a little growth here and there that would be harmed
by this practice.
Dipel: I don't know it. One problem with anything you spray on foliage,
however, is that it may promote mold, which can be a worse problem than
predatory caterpillars.
I'm still leaning toward applying Thuricide (Bt) to bait leaves, if I
can figure out which kind would attract the crawling devils. I read that
irises are particularly likely to be attacked, so I may try taking
leaves from some of the bearded irises out at the margin of the garden
(anybody looking for I. albicans?).
