Biology. This species prefers to breed in the stumps and large roots of dead or dying oaks ( Quercus spp.) ( Fagaceae) (Nardi & Mifsud 2015), but it can also breed in a number of other plants, including trees in the families, Ericaceae, Fabaceae, Fagaceae, Moraceae, Myrtaceae, Rhamnaceae, and Vitaceae, and in timber (e.g. Fisher 1950; Nardi & Mifsud 2015).
