On the No. 1 Line track this afternoon I'd stopped to photograph a sun orchid but its flowers remained closed despite occasional periods of sun. Who'd have thought flowers can get grumpy? But a few tiny Wahlenbergia flowers remained resolutely open, and I'd noticed this hover fly (Melangyna novaezelandiae) making repeated visits to this flower, so I waited until I was rewarded with this photograph.
The official common name for M. novaezelandiae is 'Large hover fly'. 'Large', needless to say, is something of an overstatement (I guess it's just to distinguish it from the 'Small hover fly', Melanostoma fasciatum).
