Biting Midge - Sphaeromias longipennis Fly IMG_0098 - Nilobezzia mallochi - male - female Biting Midges Genus Jenkinshelea - Jenkinshelea - female Dark-eyed white fly - Probezzia pallida - female Chironomidae - Probezzia pallida - female Probezzia xanthogaster - female Midge ceratopogonid - Nilobezzia schwarzii - female
Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Subphylum Hexapoda (Hexapods)
Class Insecta (Insects)
Order Diptera (Flies)
No Taxon ("Nematocera" (Non-Brachycera))
Infraorder Culicomorpha (Mosquitoes and Midges)
Family Ceratopogonidae (Biting Midges)
Subfamily Ceratopogoninae
Tribe Sphaeromiini
Synonyms and other taxonomic changes
Borkent (2014) moved all North American species other than Sphaeromias to tribe Johannsenomyiini (which had not been recognized as a suprageneric taxon in recent years).
Numbers
~50 spp. in 7 genera in our area(1), ~360 spp. in 28 genera worldwide(2)
Size
Large Ceratopogonidae, body length to 5 mm
Identification
Tarsomere 5 of female armed ventrally with stout black blunt spines (batonnets).(3) Fourth tarsomeres usually cylindrical (Wirth 1962)
Range
worldwide(2)
Remarks
Males typically do not have plumose antennae. Unlike most Ceratopogonidae and Chironomidae, where males use their antennae to listen for females, females in this tribe hunt for males. The male is usually eaten while mating.
North American genera(2):
Johannsenomyia, 2 eastern spp.
Sphaeromias, 2 spp.
Mallochohelea, 11 spp.
Nilobezzia, 4 spp.
Jenkinshelea, 4 eastern spp.; grey pollinose, wing broad with angular anal lobe
Macropeza, 1 large sp., FL; generally brown with white fore tarsi
Probezzia, 22 spp.; usually with contrasting black and white markings
