Common green bottle fly on eastern daisy fleabane. --> On a extended hike I played a bit with the macro lense and wasn't in the groove yet, but... after seven shots the battery died. So this is number seven and all I have.
The daisy fleabane (Erigeron annuus) is a North American plant species from the daisy family. It was brought to Europe beginning of the 17th century as ornamental plant. In the 18th century it "escaped" and is now widespread.
