Length 3.5 to 4 mm. Members of this genus can be difficult to identify using structural features, but general colouration and host plant are often informative. This species can be macropterous or brachypterous. The 2nd antennal segment is usually pale or dark at the base only and the head is pale with dark markings. Images in a red box indicate that the illustrated specimen is likely to be this species, but has not been checked and the image can only be said to be typical of the species.
D. pallicornis is hard to distinguish from D. stachydis, so knowing the host plant can be crucial. D. stachydis is found mainly on Hedge Woundwort and D. pallicornis on Foxglove.
- Ant3 distinctly shorter than head width across eyes
- Ant2 pale or at most dark only basally
- Tibial spines equal to or shorter than width of tibia.
This species is found on Foxglove.
