Larval form, the mandibles appear serrated when the image is magnified so it is not Hydrophilidae

Thanks Ken. I didn't know where to start with this one.

Cath, if you want to dip your toes in the water and chase freshwater macroinvertebrates two easy basic technical books (lots of pictures) are (i) The Waterbug Book by John Gooderham & Edward Tsyrlin (2002; with reprints every few years), and (ii) Colour Guide to Invertebrates of Australian Inland Waters by John H Hawking and Felicity J Smith (1997). They each have lists of references that will get you into the scientific literature.

Ditto to The Waterbug Book. Great photos and an excellent key with drawings. Thanks Ken for the other suggestion. Cheers, Sandra
