July 2014
A hover fly feeding on the nectar of dwarf marjoram in my garden on a hot and humid July day.

Summer 2014 continues with another beautiful month of above average temperatures and sunshine and below average rainfall. Rather humid and thundery at times with several spectacular overnight thunderstorms.
