Identification Key to Some Common Butterflies

Below is an identification key I created, which includes some of the most common butterfly species found in the Central Queensland area. The key uses clearly visible features such as size, colour, and spots, so may not correctly identify all variations of a species. The butterflies which make up the key are:

  • Caper White (Belenois java teutonia)
  • Small Grass-yellow (Eurema smilax)
  • Clearwing Swallowtail (Cressida Cressida)
  • Glasswing (Acraea andromacha)
  • Evening Brown (Melanitis leda)
  • Meadow Argus (Junonia villida)
  • Australian Painted Lady (Vanessa kershawi)
  • Common Grass-blue (Zizina labradus)
  • Orchard Swallowtail (Papilio aegeus)
  • Varied Eggfly (Hypolimnas bolina)
  • Common Crow (Euploea core)
