The fungus lives on trees where it forms a mat which overgrows the scales, reducing the growth of the individual parasitised scales and sometimes rendering them infertile, but protecting the scale colony from environmental conditions and predators. There are armored scale species and soft scale species. This elimination is achieved with several variations. Ants, wasps and other insects may be attracted to the sweet honeydew.
