Well here, in the extreme south, I can beat you by a few weeks with the first H. pendulus - 19th April in a woodland clearing beside the estuary.

I usually see the odd H. trivittatus in my garden during August or September but never common here.

ps. Those Van Veen ID keys look very interesting. Some of the photos didn't appear but that may be due to them not being in current use. I will print them out in case the links get broken. The Stubbs book has good keys to get to family level but thereafter they often rely on genitalia to progress to the next level; which usually makes identification of a photo impossible.
