[1] Leptocybe invasa is native to Queensland, Australia where its exact distribution has yet to be determined.

[2][3][4] L. invasa was discovered in 2000 when river red gums in the Middle East and Mediterranean began developing disfiguring galls.

Galls were collected and a previously undescribed species of chalcid wasp emerged.

[1] The adult female injects a neat line of minute eggs in the epidermis of new leaf buds on eucalyptus trees.

[9] Quadrastichus mendeli has a short developmental time[10] and has proven to be an especially effective control agent in the Mediterranean Basin.

[9] Selitrichodes neseri is another eulophid ectoparasitoid which is species specific to L. invasa and was discovered in its native Australian range in 2014 and show potential as a biological control agent on L.
