Family COLLETIDAE 



This family differs from all other bees in that the females Hne their cells with a cel- 

 lophane-like substance. The glossa is short, usually truncate or bifid, and this wasp-Hke feature 

 is the primary basis for considering the Colletidae to be the most primitive family of living bees. 

 Although the Colletidae are found throughout much of the world, the family is especially abun- 

 dant and diverse in the southern hemisphere being exceptionally well represented in Australia 

 by a large fauna consisting chiefly of the subfamilies Colletinae (ParacoUetini), Euryglossinae 

 and Hylaeinae. 



In North America the family is represented by four subfamilies of which the nominate tribe 

 of the Colletinae (Colletes) and the Hylaeinae (Hylaeus) comprise the largest assemblage of the 

 family in America north of Mexico. Only a single species of the ParacoUetini (Ettlonchopria 

 punctatissi7)ia Michener) is known to range north of Mexico into the United States (Arizona). 

 The other two subfamilies present in North America are the Xeromelissinae and Diphaglossinae 

 which occur only in the New World and are chiefly centered in the Neotropical Region. 

 Representatives of these subfamilies have been found as far north as southern Mexico 

 (Xeromelissinae) and the southern United States (Diphaglossinae). 



While most of the species in America north of Mexico depend upon a comparatively wide 

 variety of flowers for nectar and pollen, the females of a number of species of Colletes are either 

 oligoleges or exhibit narrow polylectic tendencies.
