UNTIL now the Australian blowie with the oversized booty has gone nameless. But now, she has been recognised, and named, for her most prominent feature. Her golden backside.

The species has been named Scaptia (Plinthina) beyonceae, in honour of American singer Beyonce.

CSIRO Researcher Bryan Lessard said the horse fly caught his attention while he was going through the unsorted material at the Australian National Insect Collection in Canberra.

"It was the unique dense golden hairs on the fly's abdomen that led me to name this fly in honour of the performer Beyonce as well as giving me the chance to demonstrate the fun side of taxonomy - the naming of species," Mr Lessard said.

The horse fly was first found in north-east Queensland's Atherton Tablelands in 1981 - by chance, the same year Beyonce was born. However, Mr Lessard said the three-decade delay in having the specimen described and named was not a reflection of a lack of interest. Rather specific insect groups require specific expertise for formal description and there are many thousands of insects still to be named.
