Where might soft scales be found, and on what plants?
Seven habitat types of native soft scales - all on native plants
Some native species are "host specific", meaning they can live only on particular plants, for example, the button scales [Lecanochiton species] are only found on pōhutukawa and rātā. Other native soft scales can be found on several different plants, but usually in just one habitat.
|Beech — Nothofagus species in beech forest|
|Kānuka — both kānuka [Kunzea ericoides] and mānuka [Leptospermum scoparium]|
|Lowland forest — mixed broadleaf forest types, other than podocarps and kānuka.|
|Mountain — shrubs and herbs that can sometimes be covered by snow in winter|
|Near seashore — pōhutukawa and rātā [Metrosideros species]|
|Podocarps — mostly tōtara and rimu.|
|Shrubland — often consisting of Coprosma or Hebe species|
Three habitat types of exotic soft scales - mostly on non-native plants
Some of the exotic species have very wide host plant ranges (they are polyphagous). In areas disturbed by human activity, e.g., bush margins, they can even be found on some native plants, and two of them, soft brown scale and hemispherical scale, have spread a little bit further into native forest.
|Gardens — shrubs, trees and ferns|
|Orchards — citrus, feijoa and stonefruits|
|Seashore — the ice plant scale|
Follow any habitat link, for example the link to lowland forest, and view thumbnail photos of the insects, then click on a species to find out all its known host plants and some of its biology. See also pages about the life cycle & terms, and parasitoids and fungal pathogens that can attack soft scale insects.
