Green willow leaf aphid

On this page: Identification & Distribution Other aphids on the same host

Identification & Distribution:

Chaitophorus truncatus apterae are elongate oval in shape. In spring they are pale green with three darker green interrupted longitudinal stripes. In early summer and autumn some are solidly blackish on the dorsum. Their antennae are half the length of the body, and the terminal process is 2.2-3.2 times as long as the base of the last antennal segment. The siphunculi are pale, as are the legs and antennae. The body length of Chaitophorus truncatus is 1.2-2.4 mm.

Images copyright all rights reserved.

Chaitophorus truncatus alates have separate, narrow, often broken bars across abdominal segments 3-8.

The green willow leaf aphid lives in small colonies on leavers of various narrow leaved willows including Salix purpurea, Salix alba and Salix triandra. Apterous males and oviparae can be found in autumn. Chaitophorus truncatus does not host alternate, and is not ant attended. It is distributed throughout Europe and east to Iran and Kazakhstan.

Blackman & Eastop list over 120 species of aphids as feeding on willows (Salix species) worldwide, and provide formal identification keys.


Our particular thanks to David Fenwick for his images of Chaitophorus truncatus.

Whilst we make every effort to ensure that identifications are correct, we cannot absolutely warranty their accuracy. We have mostly made 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).
