Bishop's Head gumtree gall -female

Apiomorpha pileata


A large ovoid gall about 25 mm long. The apex was truncated and the opening was a smoothly rounded slit. The gall wall was about 4 mm thick.


Spotted on the stem of a young eucalytpus tree (probably Eucalyptus radiata) in a state park ( mixed natives) - Cathedral Ranges SP.


The common name comes from the shape of the gall which looks like a Bishop's mitre.
This gall is formed by Eriococcid scale insects.
Male galls are smaller and cylindrical as seen here:
Family: Eriococcidae
