Subfamily APHIDINAE - most of the insects commonly recognised as greenfly or blackfly. 72/119 Australian species in this subfamily.
Siphunculi elongate. Cauda elongate, never knobbed. Processus terminalis at least 2/3 and usually twice or more as long as base of last antennal segment. Antennae usually 6-segmented. Eues of all formes large. Wax plates absent. First tarsal segments bearing 2 or 3 or sometimes 4 or 5 ventral hairs, without dorsal hairs. Empodial hairs and dorso-apical hairs of second tarsal segments fine pointed and usually a little shorter than the claws. Media of the forewing usually twice-branched. Apical tibial hairs not differentiated from the more proximal hairs. Mostly on Angiosperms but a few species live on Coniferae and pteridophytes.
Tribe Macrosiphini
Lateral abdominal tubercles usually absent from segments 1 and 7 but variably present on segments 2-5 or completely absent. Spiracles of abdominal segments 1 and 2 usually placed close together, their pigmented areas sometimes touching, but the spiracular apertures may be up to 3 diameters apart. Antennal tubercles often well developed. Alatae often with a dorsal abdominal black patch. Antennal hairs usually somewhat capitate, very rarely finely pointed. Media of forewing nearly always twice-branched.
Genus Micromyzus
Processu terminalis 4-7 1/2 times base VI. Ultimate rostral segment 1 1/3- 2 1/10 times hind tarzus 2 and bearing 2-12 secondary hairs. Veins of forewing often bordered with black. Dorsal abdominal pigmentation often poorly developed.

But currently only one M. katoi listed in AFD and in ALA.
Biology. Mostly anholocyclic on ferns.
