In North America, until recently, all cases of anuran myiasis were attributed to Lucilia silvarum (Meigen) or Lucilia elongata Shannon. The latter species is exceedingly rare and its life history is unknown, but L. silvarum is common and was thought to be capable of being either parasitic or saprophytic in North America. Until recently, the anuran parasite Lucilia bufonivora Moniez was thought to be strictly Palearctic, but a study in 2014 has determined this species is established throughout southern Canada. In 2019, a study demonstrated, with molecular and morphological evidence, that two adult flies formerly identified as L. silvarum and reared from amphibian myiasis cases from Canada, are actually L. bufonivora. Although the mentioned study detected relatively high genetic distances with European L. bufonivora, the lack of evident morphological differentiation suggest that they are the same species. The current study examined 12 adult males and eleven adult females morphologically from three additional North American studies. Specimens were examined which had been identified as L. silvarum or L. elongata, and they all proved to be L. bufonivora. We now suspect L. silvarum is strictly saprophagous in North America like they are in the Palearctic Region. We also provide evidence that the pattern of myiasis differs between European and North American specimens.
