Superfamily VESPOIDEA 1499 



Genus PACHODYNERUS Saussure 



Pachodynerus Saussure, 1870. Rev. Mag. Zool. (2) 22: 56. Proposed originally as a division 

 of Odynerus subg. Leionofus Sauss.; validated by Op. 893, Internatl. Comn. Zool. 

 Nomencl., 1970. 



Type-species: Odynerus {Odynerus) califoniicus Saussure. Desig. by Bohart, 1951. 



Most species nest in pre-existing cavities such as in stems, twigs, abandoned larval bagworm 

 cases, and abandoned mud-dauber cells, but one species (perhaps erroneously) has been reported 

 as also building mud nests attached to foliage. Caterpillars are stored as prey.

26: 187 (validation oi Pachodynerus Sauss., type-species Odynerus califomicus Sauss.). 

 astraeus (Cameron). Southwestern Tex. to southern Calif.; Mexico (Baja California, Hidalgo). 

 Ecology: Nests in cavities in wood, Satnbucus stems, abandoned mud-dauber cells, 

 abandoned larval bagworm cases; it is also reported, perhaps in error, as building mud 

 nests attached to leaves of growing plants. Parasite: Sphaeropthalma (Photopsioides) 

 uro (Bl.). Prey: Caterpillars. Predator: Macrosiagon c. crue^itum (Germ.).
