Ragwort patch mini-habitat

Looking at the translocated Cinnabar Moth larvae I had a chance to notice the comings and goings on the Ragwort patch. The first thing I spotted was three tiny Cinnabar larvae in addition to the original six (not four as previously stated). They must have been translocated as eggs or very tiny caterpillkars that I hadn't spotted. I also had regular vists from two Hoverflies, both of which had been recorded before - The Marmalade Fly (Episyrphus balteatus) and the Glass-winged Syrphus (Syrphus vitripennis). The latter can be difficult to distinguish from S. ribesii but between the excellent Hoverfly book and Steven Falk's photos online the ID becomes clear. There was also a mining bee but so far no ID on that. Another difficult area is Mining Bees! Photo of the male Glass-winged Syrphus clearly showing the colouring on the rear femur that distinguishes it from S. ribesii.
