Siphona Meigen 1803
Numbers
27 spp. in 6 subgenera in our area (by far the largest genus of the tribe in NA)(2)
Identification
Siphona is the only commonly encountered genus of Tachinidae with a long, thin, jointed proboscis. A few other genera have a straight or curved rigid proboscis.
Range
worldwide(3)
Food
Where hosts are known, larvae are parasitoids of Lepidoptera (except for one introduced species that parasitizes Tipulidae)(2)
Remarks
Paraphyletic with respect to Ceromya and Peribaea spp. in Stireman III, J. O., Cerretti, P., O'Hara, J. E., Blaschke, J. D., and Moulton, J. K. 2019. Molecular phylogenetics and evolution 139(106358): 1-19.

Clausicella in tribe Leskiini is similar. Most obviously it has a rigid proboscis (not jointed) and black legs (usually paler in Siphona).
