A very attractive, buttercup-like flower is putting on a show along the edges of the back yard, and while Lesser Celandine turns out to be a pretty invasive weed, I think I'm going to give it a place at our proverbial inn rather than try to completely eradicate it. The reason, besides the fact that it looks good, is that it's also an insect magnet. The local bees love the blossoms, and the waxy, sun-colored flowers have also hosted an assortment of intriguing flies. Some members of the Diptera I know, but others, like this amazing-eyed "looker," are mysteries. There are a lot of different fly species, and I may have to send this one out to the experts. I attempted an ID through the Internet, and, of course, spent time on BugGuide, but no luck. Fortunately, the Canadian government has provided a matchless resource, the Manual of Nearctic Diptera, Volumes One and Two. This entomological "Bible," however, is almost 1,500 pages long. If I live long enough, I'll get there, but clearly, the adventure isn't going to be quick and easy.
