While attempting to find, rear and photograph the 7,500 species of macrocaterpillars and their parasitoids in the dry forest, rain forest and cloud forest of the Area de Conservacion Guanacaste in northwestern Costa Rica (http://janzen.sas.upenn.edu), we have serendipituously and fortunately found ourselves to be guinea pigs and beneficiaries of the new initiative to develop DNA barcoding of species for their identification and to ferret out unnoticed species.
