Drepanaphis acerifoliae

Painted maple aphid

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

Identification & Distribution

All adult viviparae of Drepanaphis acerifoliae are winged. The alate (see pictures below) has the head and thorax reddish-brown, with three broken longitudinal white wax stripes on the head and pronotum, and white wax markings on the meso- and metathorax. There is also white wax on the anterior abdomen and posterior to the siphunculi. The wings have dark-bordered veins. The abdomen of Drepanaphis acerifoliae is somewhat paler than the thorax and bears dark dorsal tubercles at least on abdominal tergites III-IV and dark tubular siphunculi. The adult body length of Drepanaphis acerifoliae is 1.9-2.3 mm.

The painted maple aphid does not host alternate but feeds only on maples, mainly Acer saccharinum and Acer rubrum. Sexual forms comprising apterous (= wingless) oviparae and alate males occur in September and October. Drepanaphis acerifoliae is native to North America where it is common and widespread. It was introduced to Europe on its foodplant Acer saccharinum, and has previously been found in Italy, Spain and Hungary. With the record reported here (first image above), we can now include Serbia in its distribution.

 

Other aphids on the same host

Drepanaphis acerifoliae has been recorded from 15 Acer species, but mainly from Acer saccharinum and Acer rubrum.

  • Blackman & Eastop list 16 species of aphid as feeding on Silver maple (Acer saccharinum) worldwide, and provide formal identification keys.

    Of those aphid species, only 2 occur in Britain. Periphyllus lyropictus and Periphyllus testudinaceus.

    Three of the aphids found on Acer saccharinum have been found in Europe (Italy, Spain, Hungary and now Serbia) - the two Periphyllus species above plus Drepanaphis acerifoliae.

  • Blackman & Eastop list 10 species of aphid as feeding on Red maple (Acer rubrum) worldwide, and provide formal identification keys.

    Of those aphid species, only 3 occur in Britain. Drepanosiphum platanoidis, Periphyllus lyropictus and Periphyllus testudinaceus.

    Four of the aphids found on Acer rubrum have been found in Europe (Italy, Spain, Hungary and now Serbia) - the three species above plus Drepanaphis acerifoliae.

Acknowledgements

We are extremely grateful to Marko Šćiban (HabitProt) for the image of live Drepanaphis acerifoliae in Serbia, and to Mihajlo Tomić for putting us in touch with Marco.

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).
