• Paropsisterna

  leaf beetles, eucalyptus leaf beetles

  Paropsisterna is a genus of chrysomelid leaf beetles containing over 120 species native to Australia and Papua New Guinea. Many species exhibit bright aposematic coloration and feed on Myrtaceae, particularly Eucalyptus. Several species have become invasive pests in New Zealand and Europe, causing significant defoliation of eucalypt plantations and ornamental trees. The genus was redefined in 2006 to include species formerly placed in Chrysophtharta and other genera.

• Trichoniscus pygmaeus

  Least Pygmy Woodlouse

  Trichoniscus pygmaeus is a minute terrestrial isopod commonly known as the Least Pygmy Woodlouse. It is native to Britain and Ireland, with a limited introduced distribution in the United States. The species is among the smallest woodlice in its native range, measuring approximately 2.5 mm in length. Its translucent, pinkish-yellow coloration and diminutive size distinguish it from other European woodlice.
