Biology of the polyphagous, multivoltine Chrysonotomyia sp.A, an internal parasitoid of the jarrah leafminer, Perthida glyphopa , is described and morphology of the egg, 3 larval instars and pupa figured. Most frequently the female parasitoid deposits a single egg into a non‐feeding larva at the end of instar 2 or a feeding larva of instar 3. The parasitoid egg and larva develop in the liquefied contents of the host and the pupa forms within the host's mine. In the laboratory, incubation of the egg and the development of the larva required approximately 6.5 d and the completion of the pupal stage an additional 32 d. In 1986 only 3.0% larvae were parasitised at a site where the leafminer was abundant and 17.0 and 23.3% at 2 other sites where densities were low. Parasitism was inversely correlated with host density and positively correlated with the mean weekly temperature.
