Margaret love the pics especially bugs on thistle in no2. Think insects in last pic are hoverflies.

As for the cow parsley type flower - they are v difficult to tell apart without a good look at the leaves and flower structure. The plant in your pic appears to have spots on the lower stem - could be hemlock! but can't swear to it. Have been trying to find a decent pic on the net of one with a blotchy stem but doesn't appear to be one. Hemlock is often very tall so might not be that but otherwise can't tell you what it might be!
