Two ant species (Hymenoptera: Formicidae) new to the Hawaiian Islands

Ormia ochracea is a phonotactic parasite of crickets. Most flies have auditory organs located in the antennae that are adapted to detecting mating calls and wing beats in the 100 to 500 Hz range. Ormia flies have specialized auditory organs on the prosternum (similar in structure to orthopteran tympanal organs) that are used to cue in to the highfrequency (above 3 kHz) call of the male cricket (Robert et al., 1992). The ormiine cricket parasite is not native to Hawai‘i nor is the cricket (Teleogryllus oceanicus), upon which the fly is a parasite here. It is thought that the parasite was introduced to Hawai‘i along with an alien cricket, possibly in the cricket “pet trade” (crickets are kept as pets by some Asians).
