Aphids (Lachnidae)


Giant willow aphid Tuberolachnus salignus (Gmellin 1790)

Tuberolachnus salignus
  • Cambridge, 12 Nov 2000.
  • Forms clusters on willow trees and can be a pest, but this one was walking by itself on an autumn morning. Perhaps it was looking for somewhere to hibernate.
  • The largest aphid, this one has body length 5mm
  • Males of this species have not been found, reproduction is believed to be entirely parthenogenic. Winged female forms exist.


Froghoppers (Aphrophoridae)


Common Frog-hopper Philaenus spumarius (Linnaeus, 1758)

Philaenus spumarius Philaenus spumarius
  • Cambridge, 28 & 23 Jun 2001
  • Two forms of a very variable species
  • The adults of the "cuckoo-spit" nymphs
  • About 6mm long


Leaf hoppers (Cicadellidae)


Agallia consobrina Curtis, 1833

Agallia consobrina Agallia consobrina
  • Cambridge, 31 Aug 2014
  • A common species among low plants across Britain. Feeds on grass.


Balclutha punctata (Fabricius, 1775)

Balclutha punctata Balclutha punctata
  • Cambridge, 30 Aug 2014
  • Variably marked, the dark marks ranging from bold bands to non-existent, and the base colour varies to green.

  • Found on potato, mallow and sage.


Eupteryx aurata (Linnaeus, 1758)

Eupteryx aurata Eupteryx aurata
  • Cambridge, 13 Aug 2014
  • E. atropunctata is very similar, though a more greenish yellow and less strongly marked. aurata has two large dark markings on the pronotum, and may have two small ones at the front, as can just be seen here. In atropunctata the two main markings are narrower.
  • Often found on potato. This species can be a pest by damaging the chlorophyll.


Eupteryx decemnotata Rey, 1891

Eupteryx decemnotata Eupteryx decemnotata
  • Cambridge, 24 & 27 Aug 2014
  • Similar to E. melissae (below) and E. thoulessi, but those have a central dark mark on the apex while in this species the dark marks are all in pairs.
  • First noted in Britain in 2002. Like E. melissae it feeds on sage.


Eupteryx melissae Curtis, 1837

Eupteryx melissae
  • Cambridge, 24 Aug 2014
  • Usually found on leaves of sage (Salvia)
  • Also affects other herbs: balm, basil, lavender, mint, marjoram, oregano, rosemary and thyme.


Eupteryx urticae (Fabricius, 1803)

Eupteryx urticae
  • Cambridge, Mill Road Cemetery TL462583, 31 Aug 2014
  • Differs from E. cyclops in the triangle on the apex, which in cyclops extends to between the dark dots. In southern areas cyclops prefers damp habitats.
  • On nettles, as its Latin name suggests, and other low vegetation.


Japananus hyalinus (Osborn, 1900)

Japananus hyalinus
  • Cambridge, 28 Aug 2014
  • NEW TO BRITAIN. This sighting was the first from the wild received by the Auchenorrhyncha Recording Scheme; the species had previously been found on imported maple stock in garden centres.
  • Native to Eastern Asia, introduced into the USA before 1900 and to Central Europe around 1960, from where it has gradually spread.
  • Its natural food plants are Acer japonicum and A. palmatum: in Europe it has been found on Field Maple, Norway Maple and Sycamore. It is not thought to be a threat to the cultivation of these species (Walczak, Musik & Mokrzycka, 2012; Rapid Pest Risk Analysis, 2014).
  • Thanks to Dr Herbert Nickel of the University of Göttingen for identifying the photo on Flickr
  • I have written this up at greater length as the JAPANANUS HYALINUS HOMEPAGE
