Osmetrium?

	Leps-L seems to have coined a new term. The organ is the
'osmeterium'. And Scott refers to a paper by T. and Y. Meinwald which
states that the acids from osmeteria can repel ants even after they
have begun to bite the larva. (Scott fails to provide the reference
for the paper, however.) So there seems little doubt that osmeteria
can repel at least some predators.

	In Alaska, _P. machaon_ appears to space its eggs widely--I
doubt that interactions between larvae are significant.
