I found this Hover Fly about two weeks ago at Smiley Provincial Park. I believe it to be Eristalis dimidiata which is known to be active early. (I also found it last October 1 in Coldbrook so it has a long season!). Since then I have found it to be quite common in the Coldbrook area. It has an unusual habit of twitching its abdomen when perched. http://www.flickr.com/photos/58321572@N00/519026103/ Although this one acted like a bee while feeding I could not find a match for it. I wonder if it might be a Bee-Mimic, i.e. a Robber Fly. Any thoughts? http://www.flickr.com/photos/58321572@N00/519049089/ This Green Bottle Fly is very common in gardens and elsewhere & in fact, can hardly be missed if you're outdoors. This one appears to be Lucilia illustris based on its face markings. Based on their development, Blow Fly species are used by forensic scientists to determine time of death & thus help to solve crimes. I understand their larvae (maggots) are used to clean up difficult wounds in living flesh and bone!!
