Hello Soowon,
As you can see, my riend Henri Goulet tells you that this is
a Diprion species, and that the larva is different from anything
in North America.  He suggests that you contact Dave R. Smith
of the USNM in Washington, DC.

Dear Robin:

The adult is a Diprion. The larva does not fit our species. I know very
little about other Dirpion bilogy. I think that Cho should consult Dave
R. Smith in Washington (USNM) who knows the species from the region.

I do not know if you receive TAXACOM.  If not, this may interest you.
