Pink tansy aphidOn this page: Identification & Distribution Other aphids on the same host
Identification & Distribution:
Metopeurum fuscoviride is a medium-sized pink aphid with a large blackish spot on the abdomen. The antennal tubercles are very weakly developed, so that the front of head is very shallowly concave. The siphunculi are dark and thin and 1.3-2.0 times the length of the cauda. The cauda is dusky or dark, elongate triangular with a rather narrow apex, less than 1.7 times longer than its basal width. The body length of Metopeurum fuscoviride apterae is 2.2-2.9 mm.
The clarified slide mounts below are of adult viviparous female Metopeurum fuscoviride : wingless, and winged.
The pink tansy aphid mainly feeds on tansy (Tanacetum vulgare). It is regularly tended by ants, of which Lasius niger is the most common. Metopeurum fuscoviride is found throughout most of Europe.
Other aphids on the same host:
Despite the presence of toxins in tansy, many species of aphids can be found feeding on this plant. These are mostly specialists of 'garden tansy', Tanacetum vulgare (or closely related species) - plus a few polyphagous aphid species.
Blackman & Eastop list 23 species of aphid as feeding on Tanacetum vulgare worldwide, and provide formal identification keys.
Of those aphid species, Baker (2015) lists 16 as occurring in Britain: Aphis fabae, Aphis gossypii, Aphis spiraecola, Aphis vandergooti, Aulacorthum solani, Brachycaudus cardui, Brachycaudus helichrysi, Coloradoa tanacetina, Macrosiphoniella abrotani, Macrosiphoniella millefolii, Macrosiphoniella tanacetaria, Macrosiphum euphorbiae, Metopeurum fuscoviride, Pleotrichophorus glandulosus, Trama troglodytes, and Uroleucon tanaceti.
