Hey, I found a terrific and really inexpensive source for all the tobacco hornworms one could want. I'm getting mine from North Carolina State U's own insectary and they are nowhere near as expensive as Manduca project or Mulberry Farms.
Still no luck on finding anyone with Io's yet, but through another forum, I've located some sources for Cecropia, Luna, Polyphemus and such in reasonable quantity, but really, I am more interested in just Io's and sphingids.
Rather than buy the expensive hornworm [fake] feed, I'm going to wait for my natural tobacco to grow before buying a big bunch of M. sexta ova. I'll still be looking for some true tomato worms, though [M. quinquemaculata].
