Explanation of Names
Nemognatha Illiger 1807
Nemognatha - Greek for 'thread jaw'

28 spp. in 4 subgenera in our area(1), ~50 in New World, ~80 worldwide(2); selected local faunas: 4 spp. in Canada(3), 4 in NC(4), 3 in FL(5), 14 in CA(6), 1 in NH(7), 7 in OK(8), 10 in AZ
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)
Life Cycle
Females lay eggs on flowers, larvae attach to visiting bees and are carried to bee nests(11)
Remarks
mouthparts (maxillae) very long (used to suck nectar)(12)
