Tiny hoverfly

Church this morning, we're getting used to the restrictions - but not to the PA interference which caused regular loud noises. (We've been puzzled by this for some time and tried various things but it got worse and so we only used the system when essential. However, one member has tracked down the problem so we hope that's it gone for good).
After lunch went for a walk in Caird Park where there was a grand patch of mint (not sure what sort, will have to get out the book), lots of knapweed and several others things. I also met a running friend whom I've not seen since before lockdown so we had quite a chat.
On the way back I saw the heron (extra) in the burn.
