I could tell that it was a Fly, (single pair of wings, not double wings; and prominent short, sharp antennae on the front of the face). That's what I look for, anyway, in trying to start working out insects.
- So, "tick" Fly.
- It was on a piece of fruit, so, I immediately suspect a "Fruit Fly".
So, I did a Google Image Search for "Fruit Fly + Australia". OK some likely looking things pop up there.
Lets look for the "Melon Fly" - it seems to have the right shaped wings.
The detailed description there seems to fit, But I am far from being an expert. "Number of pale whitish to yellow postsutural stripes three. Subscutellum uniformly brown."
Then the description of the wing venation comes into play: "Wings with crossvein r-m covered by short, diffuse infuscation, or covered by short, well-defined infuscation; crossvein dm-cu covered by a major crossband which reaches posterior margin of wing."
My photos are OK, but not really good enough for me to trace out the veins in the wings. All I can say is that the wing structure looks "similar" between my image and this linked image.
The AQIS (Quarantine) site says: "Melon fly (Bactrocera cucurbitae) mainly affects plants such as cucumbers, pumpkins, rockmelons, squash, watermelons, but also chillies, green beans, mangoes, papayas, tomatoes, citrus and stone fruits.
"It has a worldwide distribution including China, India, Hawaii, Japan, Malaysia, Papua New Guinea, Taiwan and Thailand. It is occasionally detected on islands in the Torres Strait but is not established in Australia."I conclude that my fly on a Melon is in all probability not a Melon Fly, but something with the same sweet taste-buds.
Any Fruit Fly experts are welcome to offer advice on the ID of my Fruit Fly.
