(Gullan, P.J. & Strong, K.L., 1997) [230] (adult females of Phacelococcus)

STRUCTURE

In life, the adult females are orange-pink to yellow with an almost indiscernible waxy coating that is apparent as a white powdery deposit on the bark around the insects (Gullan, P.J. & Strong, K.L. 1997. Scale insects under eucalypt bark: a revision of the Australian genus Phacelococus Miller (Hemiptera: Eriococcidae). Australian Journal of Entomology 36: 229–240).

BIOLOGY

Gullan, P.J. & Strong, K.L. 1997. Scale insects under eucalypt bark: a revision of the Australian genus Phacelococus Miller (Hemiptera: Eriococcidae). Australian Journal of Entomology 36: 229–240 report that this species produces a large amount of honeydew in the lab and it is presumed that it is part of the diet of the Leadbeater's possum (Gymnobelideus leadbeateri McCoy) and also the yellow-bellied glider (Petaurus australis Shaw). They also state that the specimens collected in the Brindabella Range, were in longitudinal crevices in the fibrous bark on the trunk of Eucalyptus fastigata, whereas in Victoria they were found under sheets of bark of E. regnans.

SYSTEMATICS

Slide-mounted adult female with: enlarged setae absent; hair-like setae scattered over dorsal surface; dorsal multilocular pores present, abundant over both surfaces; cruciform pores absent; antennae 6-segmented; macrotubular ducts absent; microtubular ducts medium in length, with 2 sclerotized areas (see Gullan, P.J. & Strong, K.L. 1997. Scale insects under eucalypt bark: a revision of the Australian genus Phacelococus Miller (Hemiptera: Eriococcidae). Australian Journal of Entomology 36: 229–240).
