UK Nature  > Aphids  > Microsiphoniella millefolii




Common Name:   Yarrow Aphid
Scientific Name:   Microsiphoniella millefolii

Microsiphoniella millefolii, otherwise known as the Yarrow Aphid, are smallish aphids, maybe only 2-3 mm in length, with antennae longer than their body. They have a pale body with a conspicuous dark green dorsal stripe. The antennae, siphunculi and cauda (the three prongs projecting from the rear of the aphid) are black; the legs are mostly black except for the basal part of the front femur which is brown.

They live mainly on Yarrow and Sneezewort and are usually found in vegetated areas containing these foodplants. Usually found late summer and autumn. Probably quite common in Britain but badly under recorded due to its diminutive size.










www.uknature.co.uk is a website dedicated to showing the immense diversity of UK nature and wildlife. Our vast range of habitats, from lowland arable to snow covered mountains, from storm-ravaged coastlines to peaceful inland freshwater lakes and rivers, from dry, sandy heaths to deciduous and coniferous forests, all these habitats contribute to the abundance of UK nature. We have wild birds in huge numbers either residing or visiting our shores (597 recorded species as at July 2013) and we must also not forget the humble back garden with its grass lawns, flower beds filled with nectar rich flowers, shrubs and trees, all designed to attract huge numbers of insects such as bees, moths, butterflies and hoverflies; and finally the small ponds which provide safe havens for frogs, toads, newts and even slow worms and grass snakes. www.uknature.co.uk is the showcase for my personal passion, photographing uknature in all its glory. I sincerely hope you all enjoy the fruits of my labours.
