Aphalara cf. polygoni
Family: Psyllidae

Aphalara species have no genal cones and no pterostigma, and their general colouration includes shades of red and brown.

A. polygoni
is very similar to the extremely rare, northern species A. borealis, which also occurs on the same hosts. Although there may be some differences in colouring or intensity of shading of the firewing, these is insufficient information to assess this, and examination of the genitalia is currently the only way to separate the species.


Both species feed on Polygonum and Rumex species, and overwinter as adults on conifers. A. polygoni is reported to be common throughout the UK, but in recent appears appears to have been relatively infrequently reported.

Length ~3 mm
Adult: All year.
