[Taxacom] How frequent should you collect for a good representation of insect fauna?

[Soowon Cho]

Oops,
I must rewrite the phrase I wrote previously.  I said,
"This means every other week you collect, about 70% is new from the previous
collecting."
but that interpretation is wrong.  What I wanted to say is that about 70% of
the species collected from the first collecting remains not collected in the
next collecting.
Sorry for the confusion.
