Argid Sawflies (59 NA spp) have 3-segmented antennae, the third being very
elongate. Most are leaf miners. Perhaps six species of Arge
have been collected. Arge humeralis makes leaf mines in Poison
Ivy (Rhus radicans) in savanna regions. Additional species of Arge
that may be present are A. coccinea (sumac), A. clavicorne
(Amelanchier), and A. pectoralis (Corylus).
Atomocera
sp has been collected from Desmodium and
Sphacophilus
sp from Convolvulus.
