Size
5.5-15 mm
Identification
separation from Zonitis remains problematic; species are very difficult to identify, our spp. are separated by aedeagus structure(2); key to spp. in(9)
Range
Worldwide (except Australasia); throughout the New World except for the cold high latitudes(2); in our area, more diverse in the west
Season
spring, summer
Food
larval hosts: solitary bees of several families(2); adults: nectar and pollen, especially of Asteraceae(10)
