Feeding habits of the tobacco worm; it eats only five plants, all very different, but of same botanical family.
CD is puzzled by VD’s supposed hybrid tomato. If a hybrid, it would have to result from the "direct action of the pollen of a distinct species in the mother plant". CD believes this sort of inheritance occurs in varieties (though some botanists disagree), but not for species. Suggests "bud-variation".
Thanks VD for information on caterpillars selecting food plants from within one family,
and on similar behaviour in hogs, which will not eat any plants from a family containing some poisonous members.
