There has been considerable confusion about the status of the taxon piniariae. Most authors cannot find any differences between the taxa nigripes and piniariae; however, Dowden (1933) has studied the biology of the two taxa and claims that nigripes and piniariae parasitize different host species: nigripes parasitizes lymantriids and piniariae geometrids. However, Bergstrom and Bystrowski (2011) correctly point out that the way how Dowden distinguished between the two taxa is inappropriate. In addition, the assignment of the host to either nigripes or piniariae did not follow from experimental evidence, but rather from conceptual considerations (as discussed in Bergstrom and Bystrowski (2011)). In summary, the conclusions in Dowden (1933) are flawed in many aspects and in fact, there are no differences between the Blondelia flies reared from any of the hosts used by Dowden, thus removing any evidence that more than a single species of Blondelia could be involved (Bergstrom and Bystrowski 2011).
