Stable Fly

Hi Jill, nice spotting! I think this might be a different species of fly than Helophilus seelandicus. Here are some references for the Three-lined Hoverfly: http://naturewatch.org.nz/taxa/54478-Helophilus-seelandicus http://www.google.com/imgres?imgurl=http://memberfiles.freewebs.com/37/70/64177037/photos/undefined/P1000962.JPG&imgrefurl=http://www.epiphytetree.com/apps/photos/photo%3Fphotoid%3D159077896&usg=__prWv4CKD3kl1NNlvpnR76n6ktmc=&h=600&w=800&sz=234&hl=en&start=3&zoom=1&tbnid=qycpgjCUtuoF2M:&tbnh=107&tbnw=143&ei=0dQmUZqtDOrB0QGPh4HYAg&prev=/images%3Fq%3DHelophilus%2Bseelandicus%26um%3D1%26hl%3Den%26client%3Dfirefox-a%26sa%3DX%26rls%3Dorg.mozilla:en-US:official%26tbm%3Disch&um=1&itbs=1&sa=X&ved=0CDAQrQMwAg http://www.flickr.com/photos/62577675@N02/6167946851/ Your striped fly reminds me more of a species of Flesh Fly, Genus Sarcophaga.
