Philonix fulvicollis
Philonix fulvicollis is a gall wasp species in the family Cynipidae, first described by Fitch in 1859. It has an alternation of sexual and asexual generations, a phenomenon confirmed through molecular analysis of cytb and ITS2 sequences. The species is distributed across eastern and central North America, with records from the United States and Canada. Like other cynipid wasps, it induces gall formation on host plants, though specific host associations require further documentation.
Philonix gigas
Philonix gigas is a species of gall wasp in the family Cynipidae, first described by Weld in 1922. The genus Philonix is part of the diverse Cynipidae family, which comprises insects known for inducing plant galls. As with many Cynipidae species, specific biological details for P. gigas remain poorly documented in available literature. The species name 'gigas' suggests relatively large size compared to congeners, though this has not been quantified in accessible sources.
