A more recent example used DNA barcoding for the identification of cryptic species included in the ongoing long-term database of tropical caterpillar life generated by Dan Janzen and Winnie Hallwachs in Costa Rica at the ACG . In 2006 Smith " et al . " examined whether a COI DNA barcode could function as a tool for identification and discovery for the 20 morphospecies of " Belvosia " parasitoid flies ( Tachinidae ) that have been reared from caterpillars in ACG . Barcoding not only discriminated among all 17 highly host-specific morphospecies of ACG " Belvosia ", but it also suggested that the species count could be as high as 32 by indicating that each of the three generalist species might actually be arrays of highly host-specific cryptic species.
