Urn gall - female

Apiomorpha urnalis

Description:

Elongated urn shaped galls with flared free ends were spotted on stems of this yellow box. Attached to the length of the gall in Pic 1 is a calcareous tube constructed by a spittle bug nymph (froghopper) that is also a small hemipteran but from a different suborder.

Habitat:

Spotted on one of the Yellow Box trees (Eucalyptus melliodora) planted along the periphery of a playground.

Notes:

These galls are induced by small female scale insects. This wonderful spotting by Martin shows the wingless female inside the gall

Gall inducing insects are usually species specific and in some cases tissue specific on the plants they gall. Galls provide both nutrition and shelter to the developing nymph.
