Liosomaphis berberidisBarberry aphidOn this page: Identification & Distribution Other aphids on the same hostIdentification & Distribution:Liosomaphis berberidis apterae are greenish yellow or reddish orange (see pictures below) with a slight wax powdering. The antennae and legs are mostly pale, and the antennae are shorter than the body, about 0.4-0.5 times its length. The dorsum has no dark sclerites and is more or less distinctly wrinkled. The siphunculi are strongly swollen on the apical two thirds with a rather small flange, and are 1.8-2.3 times the length of the cauda. The cauda is thick and blunt. The body length of Liosomaphis berberidis apterae is 2.0-2.5 mm.
The alate Liosomaphis berberidis has the head, thorax, antennae and tips of legs darker than in the apterous viviparous female. Some tergites may have pale marginal and dorsal sclerites, sometimes fused into cross bands.
