Looking for Insect Supply Companies

[WebGardener]

In connection with a project on greenhouse and garden pests, I am seeking
to purchase a number of species and would appreciate any leads on companies
(in the United States) that sell insects.  I am willing to buy specimens
both singly, in bulk, and in display collections.

It would be most appreciated if responses could be sent directly to my
e-mail account at metasequoia at msn.com.

Thank you most kindly.
