Field Notes
Description:
About 35mm long this very brightly coloured caterpillar was apparently feeding on Exocarpos cupressiformis - 'Cherry Ballart' Deep red legs, turquiose, yellow, black and white body, turquoise head and tail.
Habitat:
Within a nature reserve incorporating stringybark, acacias, pomaderris, pittosporum, assorted woody shrubs and grasses.
Notes:
NACOPHORINI-ENNOMINAE-GEOMETRIDAE <br>
" This species has been recorded as feeding on over 17 species of unrelated plants, including: <br>
Boneseed ( Chrysanthemoides monilifera, ASTERACEAE ) <br>
Wattles ( Acacia, MIMOSACEAE ) <br>
Needlewood ( Hakea, PROTEACEAE ) <br>
Gum Trees ( Eucalyptus, MYRTACEAE ) <br>
and has also adapted to feeding on the introduced <br>
Monterey Pine ( Pinus radiata, PINACEAE ) <br>
to the point where it is a pest in pine plantations. <br> The species has been studied to discover how and why it is so polyphagus. It was found that the mean pupal size of was significantly reduced by feeding on Pinus radiata (a non-native plant host) compared to two native host plants (Eucalyptus obliqua and Acacia mearnsii). The main reason for this seemed to be the higher ratio of dry weight to wet weight of plant material in the native plants compared to the introduced plant species; the larvae on Pinus radiata simply could not get enough nutrient to catch up to those feeding on the native plant species. So given that it develops poorly on such plants, why does it continue to use them for food?

So we can now add Exocarpos cupressiformis to that list. <br>
