Leucozona Glaucia

I spent the morning in Morecambe as I had to take the car over for its annual service and MOT. It was very overcast and surprisingly cool and I took no pictures worth sharing.

On returning to Grange the sun came out and there were insects all over the Golden Rod flowers.  This one caught my eye as I had never before noticed a  blue 'hoverfly'.  Having taken its picture I came inside to consult my newly acquired copy of Brock's Insect Guide and have come to the conclusion that it is a Leucozona Glaucia.
