Looking for Leps

[mtb]

I am working at the University of Florida, and am interested in using
the gypsy moth (Lymantria dispar) and saltmarsh caterpillar
(Estigmene acrea) for some pathogenesis experiments.

Can anyone give me some leads on who may have these
commercially available, or anyone who is currently maintaining (or
has maintained) a colony?  I'd sure appreciate it, especially
regarding E. acrea, which seems to be pretty hard to find.

Feel free to contact me by email if you have any information
at                       abawden at ufl.edu

Thanks in advance!              --Alison
