Resin blocks

Invasive ant reference specimens encapsulated in clear resin provide a useful means of checking newly found ants against known problem species. The resin blocks contain examples of workers and queens of the 5 worst invasive ants - little fire ant, yellow crazy ant, red imported fire ant, Argentine ant and African big-headed ant.

A prototype has been developed, and we are currently gathering specimens of the target ants to make 30-40 blocks. These blocks will be distributed to biosecurity officers in the Pacific for use in identification.
