Explanation of Names
Nemognatha Illiger 1807
'thread-like 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
5.5-15 mm
separation from Zonitis remains problematic; species are very difficult to identify, our spp. are separated by aedeagus structure(2); key to spp. in(9)
Worldwide (except Australasia); throughout the New World except for the cold high latitudes(2); in our area, more diverse in the west
spring, summer
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)
mouthparts (maxillae) very long (used to suck nectar)(12)
