More than 60% of Australia's known insects are unnamed and a mystery to science. Of an estimated 500,000 Australian species, roughly half are insects, but many aren't categorized.

A group of sharp-eyed school students from Queensland is changing that. With the guidance of their dedicated teachers and enthusiastic experts, they've helped lift the lid on the secrets of two more insect species.

The Year 4 students from Yeronga State expected to find various insects in their Malaise insect trap. A tiny fly, first identified in a botanical garden in Portugal and unrecorded in Australia, was not one of them.

Expert analysis found that some of the fly's DNA sequences were nearly identical to a moth fly species, Alepia viatrix. They sent specimens to Germany for testing, where scientists confirmed the fly's Alepia viatrix identity. It was far from home.

The students sketched and labeled the insect, and discussed their theories of how this fly came to be in their backyard. Popular theories included it swimming the distance, stowing away on a shipping container, or attempting world domination.
