The giant aphid Stomaphis wojciechowskii Depa and its specialist hymenopteran parasitoid Protaphidius wissmannii Ratzeburg are both recorded as new to Britain on the basis of specimens collected during 2018 from multiple sites in northwest Cambridgeshire (United Kingdom). We briefly describe the biology and ecology of the aphid. Molecular analysis...
The first description of the hitherto unknown alate morph of the recently discovered giant aphid species Stomaphis wojciechowskii Depa is presented, based on examination of specimens collected in the United Kingdom and Poland in 2018. A key for the determination of known alate morphs of the genus Stomaphis is provided. Morphological comparisons are...
