  Uroleucon is a large genus of medium-sized to large aphids. They occur in Europe, Asia, Australia, and North and South America. There are 226 described species of Uroleucon worldwide, at least 71 in North America north of Mexico, and at least 2, probably many more, in Minnesota. Unlike many aphids, they are not attended by ants. They All but one species feeds on plants in the Aster (Asteraceae) family. Unlike most aphids, they complete their life cycle on one host. They do not migrate to a secondary plant species.      
           
 
Description
 
 

Uroleucon aphids are soft-bodied, somewhat pear-shaped, and to 516 (4 to 8 mm) long. They may be red, reddish-brown, or blackish-brown. The antennae are about as long as the body. There is a pair of elongated processes (cornicles) near the end of the abdomen.

Uroleucon aphids are specialist feeders, feeding on just one plant species or a few related species. They can often be identified by the plant host species. However, some plants host multiple species of aphids. There are at least 22 species that feed on goldenrods (Solidago spp.).
