Marchalina hellenica is a scale insect that lives in the eastern Mediterranean region, mainly in Greece and Turkey. It is an invasive species in Melbourne, Australia. It lives by sucking the sap of pine trees, mainly the Turkish pine and, to smaller extent, Aleppo pine, Scots pine and stone pine. It can be found in the cracks and under the scales of the bark of these trees, hidden under the white cotton-like wax it secretes. Its main form of reproduction is parthenogenesis.
