The Eupatorium in our garden is in full bloom and the insects are loving it. Here are some pics from a single 1/2 hour photoshoot (there were others too - some fast, small buggers that I just wasn't able to get). I'm working on the IDs of the less obvious ones...
...update: All bugs identified. And I take no credit for most of them - the fine folks over at BugGuide.net are the real experts. Thanks.
(thanks again, BugGuide!)
I was sure that this was the same species as the one above,
but Richard V. over at BugGuide.net has set me right
An introduced species, first recorded in the U.S. in Boston, 1978.
Expanding range in the U.S. and possibly replacing native species
