TRIEPEOLUS MESILLAE 
(HYMENOIYfERA: APOIDEA) IN ILLINOIS: A 

CLEIYfOPARASITIC 
BEE NEW TO THE EASTERN UNITED STATES 

Cockerell (Ann. Mag. Nat. Hist., Ser. 7, 13:33-42,1904) named Triepeolus mesillae on the 
basis of a series of specimens which he collected at Mesilla, New Mexico. A second locality 
for the species was added by Rozen (Amer. Mus. Novitates 2244, 1966) when he described 
the larva of T. mesillae from cells of Nomia (Epinomia) triangulifera Vacha! excavated by 
E. A. Cross at Lakeview, Douglas County, Kansas, in 1955. Aside from Cockerell's in­
elusion of T. mesillae in his key to the Triepeolus of Colorado (Cockerell, Univ. Colorado 
Stud. 
16:99-126, 1928), no other information concerning the species has been published. The purpose of 
this paper 
is to record T. mesillae from Illinois and thus to provide a third locality 
for the species and the first from east of the Mississippi River. 
On 29 
August 1981, 
an associate of the author, Tamara F. Bouseman, took a male and a 
female o  Triepeolus mesillae from flowers of Helianthus occidentalis Riddell in Henderson 
County, Illinois. The bees were collected between 1300 and 1400 CDST from a population f
H. occidentalis growing In a sand prairie about 3.5 miles N of Oquawka. During the time of 
the collection of the two specimens of T. mesillae, the author collected a pollen-laden female 
of 
the recorded host, 
Nomia triangulifera, from nearby flowers of Helianthus rigidus (Cass.) 
Desf., and other specimens of N. triangulifera were taken from sunflowers later on that day 
(Bouseman, J. Kansas Entomo!. Soc., 55:95-96, 1982).
