Identification & Distribution

Adult apterae of Macrosiphoniella tapuskae are pale to dark green (see first and second pictures below) often with a darker green area on the dorsal abdomen between the siphunculi and a dark spot in front of each siphuncular base. A reddish-brown form has also been observed (see Invertebrados Insectarium Virtual). They have previously been described as 'not wax-powdered', and those we found in southern England had no wax powder. However, specimens identified as Macrosiphoniella tapuskae on Achillea from Serbia have heavy wax deposits (see third picture below), as have those found in Spain (see Invertebrados Insectarium Virtual). The antennae are rather dark with the terminal process 4.2-5.3 times the length of the base of antennal segment VI. The body hairs are quite long and not placed on distinct scleroites (cf. Macrosiphoniella sejuncta, which has body hairs on small dark scleroites). The siphunculi are mainly (light or dark) brown with paler bases, very slender with dilated base and apex, reticulated on the apical 12-18% and 1.8-2.3 timesas long as the cauda (cf. Macrosiphoniella millefolii, which have siphunculi 0.8-0.9 times the length of the cauda). The cauda frequently has more than 19 hairs. The body length of adult Macrosiphoniella tapuskae apterae is 2.0-2.5 mm.

The alate Macrosiphoniella tapuskae has mainly dark siphunculi but with a paler thickened base.

The clarified slide mounts below are of adult viviparous female Macrosiphoniella tapuskae : wingless, and winged.

Macrosiphoniella tapuskae most commonly feeds on yarrow (Achillea millefolium), wild chamomile (Matricaria chamomilla), pineappleweed (Matricaria discoidea) or scentless mayweed (Tripleurospermum inodorum), but can also be found on other genera within the tribe Anthemidae. On yarrow it usually feeds on the lower leaves and is said to prefer plants growing in dry sandy places. It is found throughout Europe eastward through Russia into central Asia, North Africa and North America.


Other aphids on same host:

  • Macrosiphoniella tapuskae has been recorded from 9 Achillea species (Achillea biebersteinii, Achillea crithmifolia, Achillea ligustica, Achillea micrantha, Achillea millefolium, Achillea nobilis, Achillea ptarmica, Achillea santolina, Achillea setacea).

    Blackman & Eastop list 46 species of aphid as feeding on yarrow (Achillea millefolium) worldwide, and provide formal identification keys (Show World list). Of those aphid species, Baker (2015) lists 26 as occurring in Britain (Show British list).

  • Macrosiphoniella tapuskae has been recorded from 2 or 3 Matricaria species (Matricaria chamomilla, Matricaria discoidea and Matricaria matricarioides =Matricaria discoidea??).

    Blackman & Eastop list 26 species of aphid as feeding on Matricaria species worldwide, and provide formal identification keys (Show World list). Of those aphid species, Baker (2015) lists 21 as occurring in Britain (Show British list).


We are extremely grateful to Mihajlo Tomić for the image of live wax-powdered Macrosiphoniella tapuskae in Serbia. Our thanks also to Roger Blackman for images of his clarified slide mounts.

We have made provisional identifications from high resolution photos of living specimens, along with host plant identity. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. We have used the keys and species accounts of Blackman & Eastop (1994) and Blackman & Eastop (2006) supplemented with Blackman (1974), Stroyan (1977), Stroyan (1984), Blackman & Eastop (1984), Heie (1980-1995), Dixon & Thieme (2007) and Blackman (2010). We fully acknowledge these authors as the source for the (summarized) taxonomic information we have presented. Any errors in identification or information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006).
