THE APPEARANCE OF VESPULA SQUAMOSA DRURY 
IN MISSOURI 
By Phil Rau, Kirkwood, Missouri 
Carl D. Duncan 1 2 regards as Vespula maculijrons Buyss. the 
yellow jacket about which I have published two papers as Vespa 
germanica r Recently Miss Grace A. Sandhouse likewise named 
specimens submitted to her for examination as Vespula maculi- 
jrons. 
In the spring I have always liked to watch the queens hunting 
for nesting sites, and for many years the clay bank in my gar- 
den, with its many crevices and old wasp and bee burrows, was 
a favorite hunting area. During the past three years, however, 
I occasionally saw searching about the clay bank a Vespula 
queen that differed somewhat in color from what I was accus- 
tomed to seeing. Upon submitting a specimen to Miss Sand- 
house for identification, I learned that the species is Vespula 
squamosa Drury (= V. Carolina). This I think is the first 
record for this wasp in Missouri. 
Lewis, in his paper on “Vespinae of the U. S. and Canada” 
(Trans. Amer. Ent. Soc. 24:180-181, 1897) gives its habitat 
under the name V. Carolina as Pennsylvania, and under the 
name V. squamosa as New York. Turner, in his paper “The 
Workers of V. Carolina resemble in Coloration the Males” 
(Psyche 15:1-3, 1908), records digging up a large nest at 
Atlanta, Georgia. 
How generally V . squamosa is established in Missouri is not 
known, but at Kirkwood I am sure I have seen the queens for 
at least three years.
