The following information was extracted from the document "A Seven Year Plan for an Inventory of the Diptera of Costa Rica" (September 1998) by D.M Wood and Manuel Zumbado and up dated with recomendations of the Diptera Taxonomic working group follow up workshop held on June 2000.

For its size, Costa Rica must have one of the most diverse faunas of any country in the world. Unfortunately, however, the taxonomy of most of the families of Costa Rican flies is not well developed, especially among families in which the flies themselves are very small. We estimate that there are between 20,000 and 30,000 species of flies in Costa Rica, but scarcely 900 of these have been recorded in the literature. A recent survey of the tachinid literature revealed that fewer than 5% of the expected species of Tachinidae have been mentioned from Costa Rica, and the same is true for most other families, of which there are almost 90 so far recorded in Costa Rica.Tabanidae, Mosquitoes (Culicidae) may be an exception, however, because the group is well known in the Neotropical Region, but even for mosquitoes it is not possible at the present time to state precisely how many species are found in Costa Rica.

On May 29 1998, the Diptera Taxonomic Working Group (TWIG) met to develop sampling and curatorial protocols to maximize the data to be obtained by the Diptera TWIG.

In June 11-15, 2000 some of the Diptera TWIG members met in Monterverde to evaluate the process of collecting, mounting and identification of specimens. Likewise, the strategy for the Manual of the Diptera of Costa Rica was defined.
