The tobacco hornworm, _Manduca sexta_, lab in our biology department is
led by Larry Schwartz who got his PhD from Jim Truman in Seattle.  They
use an interesting method of simulating the burrowing chambers of the
tobacco hornworm in their _M. sexta_ breeding factory.  They drill into
a 2x4 in the 4" direction with a large bore (ca. 1") brace and bit.  The
wandering larva is placed in this deep chamber and corked shut.  The
chamber seems to be perfect for this sphingid to pupate.
