notes

Mining sawfly larvae in general have an extremely restricted palate, and it is surprising that F. nigrita forms such a clear exception to this rule. Liston (1993b) therefore has suggested that the species in fact may consist of a complex of microspecies.

Among hundreds of reared specimens Hering (1924a) did not find a single male; apparently the species is parthenogenetic.
