Subfamily Macropodaphidinae

Biology

The Macropodaphidinae is a small subfamily of 6 species in 1 genus (Macropodaphis). Most species feed on cinquefoils (Potentilla spp.), but three species have other hosts recorded, including Artemisia and Carex. Their life cycles are unknown, and not much is known regarding their hosts. They are found in the steppe zones of Central Asia (central & eastern Palearctic). The fossil alate aphid Megapodaphis monstrabilis found in Baltic amber is closely related to Macropodaphis.

 

Morphology

Adult Macropodaphidinae viviparae may be apterous or alate. These aphids are weakly wax-powdered; there are also short white stalks of wax secreted from the dorsal body glands. The head and pronotum are separated. The anterior margin of the eyes reach to the base of the antennal socket, and the occiput is extended posteriorly beyond the hind margins of the eyes. The clypeus is greatly enlarged. The eyes are compound, with the ocular tubercle distinct, but small. The terminal process tapers evenly from base to apex. The accessory rhinaria are scattered, not concentrated in one area. The second rostral segment has well developed wishbone-shaped stiffening. The dorsum has transverse rows of numerous tubercular processes bearing hairs and wax glands.

The fore femora are much enlarged and adapted for jumping (see picture above of Macropodaphis paradoxa). The fore legs also have stronger tibiae and tarsi than the other legs. The empodial hairs are simple. The siphunculi are short, cylindrical, without a flange, and placed on tergite VI. The cauda is knobbed and the anal plate indented. Oviparae are apterous, but males are unknown. The oviparae do not have subsiphuncular gland plates, and scent plaques are only on the hind tibiae.
