Hoverfly

Hoverfly

Observation - Hoverfly - UK and Ireland. Description: The three white lines across the abdomen? I can only find one species like this in my book which is quite rare - Eristalis cryptarum. Seems to prefer freshwater margins too and this was near chalk grassland. Must be something else surely.
