Ceruraphis eriophori
(Walker, 1848)
Wayfaring Tree-sedge Aphid
Ceruraphis eriophori is an with a heteroecous involving alternation between Viburnum species (primary hosts) and sedges or related plants (secondary hosts). In North America, it has been collected from curled leaves of Viburnum and V. opulus in New Brunswick, and from V. opulus var. roseum in Colorado. The species also occurs in Europe, where secondary hosts include Carex, Eriophorum, Luzula, and Typha; in North America, Cyperus virens is the only reported secondary host. Activity peaks in spring and autumn on primary hosts.
