The beech forests (Nothofagus sp) of New Zealand's South Island host two scale insects
that in turn produce honeydew. Bees collect this resource to produce a honeydew that
is dark in colour and full of minerals, oligosaccharides and dextrins. The whiskers
here are a filament from the scale insect that is used to excrete the waste sap as
honeydew. Other organisms such as moulds and fungii also grow on this resource and
their growth on the trunks and branches turns the trees black. The main species in turn
is called "Black Beech".
