Distribution. Endemic. Galápagos: Baltra, Bartolomé, Darwin, Española, Fernandina, Floreana, Isabela, Marchena (ICCDRS), San Cristóbal, Santa Cruz, Santa Fé, Santiago (ICCDRS), Seymour.

Remarks. Adults of G. inoa ( Fig. 26 ) are collected primarily from littoral and arid zones and have been observed visiting flowers of Scalesia ( Boada 2005) . A single specimen was reared during the 1989 expedition from a puparium collected from exposed east Pacific green sea turtle ( Chelonia mydas L.) eggs. Some eggs from the nest were completely filled with empty puparia.

In a study conducted by the CDRS, larvae of this species emerged from a tortoise on Santiago, with the larvae dropping and tunneling immediately into the sand. There were also observations of live larvae in tortoise eggs from intact nests, as well as larvae were found in sick and dying hatchlings. The percentage of parasitism was considered to be low.
