Calliphora bryani Kurahashi

Rawaki Blow Fly (Calliphora bryani)

The Rawaki Blow Fly is obviously endemic to the island of Rawaki, where it feeds upon the carcasses of dead seabirds.

It is an about 0,5 to 0,7 cm long fly with a reddish-brown thorax, which is silver-grey dusted throughout. The abdomen is glossy bronze in color, the legs are reddish brown. The wings are hyaline.

The Rawaki Blow Fly is viviparous, that means it doesn’t lay eggs but gives birth to fully developed larvae.

Trupanea celaenoptera Hardy

Brown-winged Fruit Fly (Trupanea celaenoptera Hardy)

The Brown-winged Fruit Fly from the island of Hawai’i is related to the Black-winged Fruit Fly (Trupanea nigripennis Hardy).

The species reaches a length of about 0,42 cm and has about 0,44 cm long, almost completely brown colored wings.

The larvae of this species feed on the plant tissue of several (?) Dubautia spp., whereby they cause galls on the stems of the plants they afflict.

~~~

The larvae themselves again, are obviously parasitized by the native Metallic Glossy Eulophid Wasp (Euderus metallicus (Ashmead)).
