A contribution to the biology of North American Vespine wasp

[Anthony Daglio]

Here is a link to a downloadable copy of Carl Duncan's A contribution to the biology of North American Vespine wasps: http://www.academia.edu/4894080/Duncan_ ... pine_wasps

This is a very detailed work on the biology of the mainly western north american vespine fauna. This work also gives a very detailed description of the morphology of the western yellowjacket; Vespula pensylvanica and provides many figures and photos as well.
