Eucalyptus Leaf Galls

Description:

These were attractive thin-walled urn-shaped galls that appeared to be about 10 to 12 mm tall. The apical openings through which the adults would have emerged had jagged edges which were a deep pink. This colour bled into the pale green bodies and bases of the galls.

Habitat:

Spotted on the upper surface of eucalyptus leaves - species not known.

Notes:

These galls are formed by small hemipterans called psyllids, often referred to as plant lice. The adult emerges out of the galls by erupting through the apex forming the star-shape margins.
